The Mathematics Department at the University of Virginia offers graduate students the opportunity to do research in a wide range of specialties. To help students with the daunting task of planning their multi-year program, in this guide we describe standard routes through the main research areas that students can currently pursue. We expect most students to follow one of these paths.
For convenience, we have grouped these within Programs in Algebra, Analysis, Topology, and the History of Mathematics. However, it is to be emphasized that there is much interaction between these, and a course of study might easily fall between areas. Furthermore, research areas undergo constant change due to changing faculty and student interests, and to new faculty joining the Department. Finally, there are a number of possible courses of study not listed here that may involve collaboration with faculty from other departments.
Graduate research in algebra is organized into the following areas:
The following is the list of basic, graduate courses in algebra prerequisite for students intending to pursue studies in algebra:
Students also take one additional algebra course in one of the two semesters.
Besides taking the sequence MATH 7751, 7752, 7753, 7754 in their first two years, students with interests in algebra are required - within the first two years - to take at least one additional course in the specialized area of algebra which they expect to follow. The additional course(s) may be an independent reading course taken under the supervision of a faculty member.
The General Exam in Algebra is based on the material of MATH 7751, 7752.
Algebra students are also required to take and to participate actively in MATH 9950 (Algebra Seminar) every semester after the first year. In the first semester of the second year, students contemplating working in algebra should contact a faculty member regarding a topic for a literature survey and, during the second semester, give a short expository talk in the Algebra Seminar.
In the second year, students take the Second-Year Proficiency Exam, which, in algebra, consists of a conversation with a panel of faculty members on the material of two or three second-year algebra courses taken by the student, and on the bibliographical research done by the student and presented in MATH 9950.
Research in this area focuses on structural, combinatorial and homological properties of linear groups over general rings with a special emphasis on arithmetic rings (i.e., the rings of S-integers in global fields). Topics include the normal subgroup structure of the groups of rational points of algebraic groups and of their important subgroups, finiteness properties of arithmetic groups in positive characteristic, the rigidity of representations of finitely generated groups and building theory, in particular, group actions on spherical, affine, and twin buildings. The work in this area requires methods of the theory of algebraic groups, algebraic number theory, homological algebra, and combinatorial geometry/topology.
MATH 7600 Homological Algebra, MATH 8851 Group Theory, MATH 8600 Commutative Algebra, MATH 8620 Algebraic Geometry, and special topics courses (or reading courses) in algebraic groups, arithmetic groups, geometric group theory, algebraic number theory, and building theory.
Representation theory deals with representations of algebraic and associated finite groups, associative and Lie algebras, and connections with algebraic geometry and mathematical physics. Topics include representations of reductive algebraic groups in positive characteristic with applications to finite groups of Lie type, quantum groups and Hecke algebras, quasi-hereditary algebras and vertex algebras. This work used methods from the theory of algebraic groups and algebraic geometry, Lie algebras, and homological algebra.
MATH 7600 Homological Algebra, MATH 8851 Group Theory, MATH 8852 Representation Theory, MATH 8620 Algebraic Geometry, MATH 8700 Lie Groups, MATH 8710 Lie Algebras, and special topics courses (or reading courses) in algebraic groups, Kac-Moody algebras, symmetric groups and their representations, Hecke algebras and quantum groups.

Commutative algebra studies the space of solutions of polynomial and power series equations in many variables, often by creating a "generic" solution space, and investigating the properties of this space, and its specializations and deformations.
In the early 20th century, commutative algebra was born out of three classical fields: algebraic number theory, algebraic geometry, and invariant theory. Today it retains connections to all of these areas, as well as many other areas such as combinatorics, homological algebra, representation theory, computational algebra, singularity theory, and algebraic statistics.
One of the most important techniques in modern commutative algebra is that of reduction to characteristic p, and the study and classification of singularities through invariants coming from this reduction.

Graduate research in analysis is organized into the following areas:
Students intending to do research in some area of analysis must take the following courses:
Additional courses and requirements depend on the specific research area selected by a student, as specified below.
The General Exam in Analysis has two parts: the first part based on material from MATH 7310, and the second part based on material from one of MATH 7340, MATH 7250, and MATH 7360. For students planning to work in analysis, the second part of the general exam should fit with the area they are pursuing.
Students in analysis in the second year and beyond are expected to participate in one of the analysis research seminars. These seminars are an important component of the graduate program, and are student-oriented. They aim to expand upon material covered in the various courses and to prepare students for independent reading of research papers.
In the first semester of the second year, students contemplating working in an area of analysis should contact a faculty member regarding a topic for a literature survey, and, during the second semester, give a short talk in the appropriate seminar.
Also in the second year, students take the Second-Year Proficiency Exam, which, in analysis, consists of a conversation with a panel of faculty members on the material from two or three second-year analysis courses, and and on the bibliographical research done by the student for their seminar presentation.
This area focuses on the qualitative study of solutions of differential equations: ordinary differential equations (ODE's) as well as partial differential equations (PDE's), both linear and nonlinear. Particular emphasis is placed on equations arising in mathematical physics and related areas of applied mathematics. Topics of study include fluid dynamics, linear and nonlinear elasticity and wave propagation, harmonic analysis, dynamical systems, and control theory. The mathematical methods used draw from real and complex analysis, functional analysis, harmonic analysis, ordinary and partial differential equations, basic differential geometry, and probability.
Besides the three common core analysis courses, students should also take MATH 7250 (Ordinary Differential Equations I) as soon as possible. In the second year, students should take MATH 8250 Partial Differential Equations I, and, if possible, MATH 7320 (Real Analysis II) and MATH 7420 (Functional Analysis II). They should also begin attending MATH 9250 (Differential Equations Seminar). Students should try to take the General Exam in analysis on MATH 7310 and MATH 7250; however, the combination of MATH 7310/7340 is also acceptable.
MATH 726 (Ordinary Differential Equations II) and MATH 826 (Partial Differential Equations II), possibly in reading course format. Also MATH 7360 (Probability), MATH 8310 (Operator Theory I), MATH 8360 (Stochastic Differential Equations), MATH 7450 (Mathematical Physics), and MATH 8720 (Differential Geometry).
Our research in mathematical physics is concerned with the spectral and scattering theory for Schroedinger operators in quantum mechanics, equilibrium and non-equilibrium statistical mechanics, and topics in classical mechanics. The mathematical methods needed include: real analysis–measure theory and integration; functional analysis–for example, operators in Hilbert spaces; Fourier analysis; partial differential equations; and some basic probability theory.
Besides the three common core analysis courses, students should also take as soon as possible MATH 7250 (Ordinary Differential Equations I). In the second year, students should take, if possible, MATH 7320 (Real Analysis II), MATH 7420 (Functional Analysis II), MATH 7450 (Mathematical Physics), and participate in MATH 9450 (Mathematical Physics Seminar). Math physics students should take their General Exam in analysis on MATH 7310 and MATH 7340.
MATH 8250 (Partial Differential Equations), MATH 7360 (Probability), MATH 8450 (Topics in Mathematical Physics) as appropriate to the student's thesis work.
Our research on Hilbert space operators draws broadly from functional analysis and has two main (interrelated) strands. One is rooted in complex function theory and concerns composition, Toeplitz, and other operators on spaces of analytic functions. The other studies algebraic structures of operators: von Neumann algebras, C*-algebras, operator spaces, and noncommutative function spaces.
Besides the three common core analysis courses, students should take MATH 8310 (Operator Theory) or MATH 8300 (Function Theory) by the end of their second year. Also in the second year, students should take, if available, one or both of MATH 7320 (Real Analysis II) and MATH 7350 (Complex Analysis II), as well as MATH 7420 (Functional Analysis II). Beginning in the second year, students should participate in MATH 9310 (Operator Theory Seminar). Students should take their Ph.D. General Exam in analysis in MATH 7310 and MATH 7340.
MATH 7250 (Ordinary Differential Equations), MATH 7360 (Probability Theory), MATH 7450 (Mathematical Physics), MATH 8250 (Ordinary Differential Equations), MATH 8320 (Operator Theory II), MATH 8400 (Harmonic Analysis).

Areas of particular interest to faculty include central limit theorems, Malliavin calculus, stochastic differential equations, Markov and Lèvy processes, stochastic networks, measure-valued processes, and applications to operations research and mathematical biology.
Besides the three common core analysis courses, students should take MATH 7360 (Probability Theory I) and MATH 737 (Probability Theory II) as soon as possible. These are typically offered in the Spring and Fall respectively, so that students can begin in the Spring of their first year after taking 7310. In the second year, students should take MATH 8360 (Stochastic Calculus and Differential Equations). Students should also participate in MATH 9360 (Probability Seminar). Students should take their Ph.D. General Exam in analysis in MATH 7310 and MATH 7360.

Graduate research in topology is organized into the following areas:
We must emphasize that these areas have a lot in common, so the subdivision into "algebraic" and "geometric" is not always precise.
The following is the list of basic graduate courses prerequisite for students intending to pursue research in topology:
The course MATH 7830 will be offered in the Spring semester each year. Besides taking the sequence MATH 7820 (or 5770), 7800, 7810, 7830, students with interests in topology are required–within the first two years–to take at least one additional course in the specialized area or track of topology (see below) which they expect to follow. These additional courses may be independent reading courses taken under the supervision of a faculty member.
The General Exam in Topology is based on the material of MATH 7820 (or 5770), 7800.
Topology students are expected to take and to participate actively in either MATH 9800 (Topology Seminar) or MATH 9820 (Geometry Seminar) every semester after the first year. Research seminars are an important component of the graduate program. Participation in them gives students an opportunity to be exposed to the current research in topology. In the first semester of the second year, students contemplating working in topology should contact a faculty member regarding a topic for a literature survey and, during the second semester, give a short expository talk in the Topology or Geometry seminar.
In the second year, students take the Second-Year Proficiency Exam, which, in topology, consists of a conversation with a panel of faculty members on the material of two or three topology courses taken by the student during the second year, and on the bibliographical research done by the student and presented in MATH 9800.
The subject of algebraic topology is the interplay between topology and algebra. One associates algebraic objects, e.g., groups and rings, with topological spaces in a 'natural' way, and investigates how the algebraic invariants reflect the topological structure of the spaces. Research in this area requires a good understanding of both topology and algebra. Areas of particular interest to faculty include homotopical algebra and homotopy as organized by the calculus of functors, group cohomology and its connections to representation theory and algebraic K-theory, and the study of complex oriented cohomology theories. There are deep connections with many parts of algebra, including algebraic geometry and number theory, and mathematical physics.
MATH 7840 Homotopy Theory, MATH 8800 Generalized Cohomology, MATH 7600 Homological Algebra, MATH 8700 Lie Groups, MATH 8650 Algebraic K-Theory, MATH 8830 Cobordism and K-Theory, and special topics (or reading courses) in calculus of functors and homotopical algebra.
The central subject of geometric topology is the theory of manifolds, their classification, and study of their geometric properties. Research areas represented by the faculty include knot theory, quantum invariants of three-dimensional manifolds, geometric and differential four-dimensional topology, gauge theory, groups acting on manifolds, hyperbolic geometry, and moduli spaces of geometric structures. This area has deep connections with algebraic topology, representation theory, geometric analysis and mathematical physics.
MATH 8750 Topology of manifolds, MATH 8830 Cobordism and K-Theory, MATH 8720 Differential Geometry, MATH 7840 Homotopy Theory, and special topics courses (or reading courses) in characteristic classes, knot theory, 4-dimensional topology.

The graduate program in the history of mathematics includes a component in the history of science taken within the Department of History. Students in the program must satisfy all of the requirements for the Ph.D. in Mathematics. In particular, they must complete the coursework in mathematics and perform satisfactorily on General Examinations in two areas before they are permitted to proceed toward the doctorate. Strong reading competency in either French or German is required for admission into the program, with strong reading competency required in the other language by the time dissertation research begins. Depending on a particular student's interests, other languages may also be required.
Program Coursework The following is typical for a student in the graduate program in the history of mathematics:
Additional mathematics courses to complete the number of hours required for the degree (chosen in consultation with the adviser), and any additional courses as needed (in, for example, language(s), history, or philosophy).
Students are expected to participate actively in MATH 9010 History of Mathematics Seminar in all semesters.
For students in this program, the proposal defense replaces the Second-Year Proficiency Exam. It generally takes place before the end of the third year. Successful defense of the proposal represents "permission to proceed" to the dissertation phase of the program. The proposal is a written document (generally thirty to forty pages in length, exclusive of bibliography) that is presented in a public forum. It
