# Introduction to Modular Forms

This course ran from January to March 2005.

# You probably want to visit the new course's homepage.

### Aims and Objectives:

Modular forms are classical analytic objects which were the subject of
much interest early in the last century. For some time their interest
appeared to have diminished, until remarkable connections with a huge
range of other areas in pure Mathematics were discovered. The most
celebrated is, of course, the role they played in the proof of Fermat's
last theorem, through the conjecture of Shimura-Taniyama-Weil that
elliptic curves are modular, but they also occur in group theory amongst
other things. Therefore there is much current interest in the theory of
modular forms. The aim of this course is to cover the classical theory
of modular forms.
### Syllabus

This will include such material as:

- Definitions of the modular group, congruence
subgroups, modular forms
(defined for congruence subgroups as well as SL_2(Z), a difference
from Serre's book)
- examples, Eisenstein series, lattice functions
- Some number theoretic applications
- space of modular functions
- expansions at infinity, zeroes and poles using contour integrals
- Hecke operators
- Some Atkin-Lehner theory
- Peterson inner product
- Eigenforms
- L-functions and some properties
- Theta functions.
