MA4H9 Modular Forms

Not running in 2017/18.

Lecturer: Guhanvenkat Harikumar

Term(s): Term 1

Status for Mathematics students: List C

Commitment: 30 lectures, plus a willingness to work hard at the homework.

Assessment: 85% by 3-hour examination, 15% assessed work.

Prerequisites: MA231 Vector Analysis. Additionally, MA3B8 Complex Analysis is highly recommended although not strictly required. Please talk to me if you have not yet taken MA3B8 and still want to take this course.

Leads To: Ph.D. studies in number theory and algebraic geometry

Content: The course's core topics are the following:

  1. The modular group and the upper half-plane.
  2. Modular forms of level 1 and the valence formula.
  3. Eisenstein series, Ramanujan's Delta function.
  4. Congruence subgroups and fundamental domains. Modular forms of higher level.
  5. Hecke operators.
  6. The Petersson scalar product. Old and new forms.
  7. Statement of multiplicity one theorems.
  8. The L-function of a modular form.
  9. Modular symbols
