## First-Year Courses in the Graduate Program

The courses described below are the core of the first year graduate program. The program undergoes regular reevaluation and change, so the list of topics is only approximate, and the content of the courses also varies from year to year at the discretion of the instructor.

### Analysis

#### Math 312: Analysis I

Measure theory, integration and $$L^p$$ spaces, differentiation, basic functional analysis. Additional topics may be discussed depending on the instructor.

Taught in Fall 2016 by Luis Silvestre.

Prerequisite: Graduate student status or instructor consent

#### Math 313: Functional Analysis

Weak convergence, compact operators, spectral theory, Sobolev spaces, and some applications. Additional topics may be discussed depending on the instructor.

Taught in Winter 2017 by Charles Smart.

Prerequisite: Math 312

#### Math 314: Complex Analysis and Topics in Analysis

Basic complex analysis, Cauchy theorem in the homological formulation, residues, meromorphic functions, Mittag-Leffler theorem, Gamma and Zeta functions, analytic continuation, mondromy theorem, the concept of a Riemann surface, meromorphic differentials, divisors, Riemann-Roch theorem, compact Riemann surfaces, uniformization theorem, Green functions, hyperbolic surfaces, covering spaces, quotients.

Taught in Spring 2017 by Gregory Lawler.

Prerequisite: Math 313

### Geometry and Topology

#### Math 317: Algebraic Topology
