The seminar will meet weekly at the Student Lounge or Thesis Room, from 4:00pm-5:00pm on Friday. The official homepage for the seminar is here.
I will be talking about various aspect of classical modular forms, especially its application in number theory. My first goal is to give you a fundamental treatment of modular forms, a first course if you will (which mean that it comes with little pre-requisite and could be viewed as a typical graduate course like algebraic topology).
The (incomplete list of) topics I want to talk about are:
- Definition of modular forms; most importantly, precise definition of various notions such as cusps, Fourier expansion and holomorphic at cusps; work out examples of modular forms notes
- Interpretation of modular forms as differential on modular curves notes
- Dimensions of the vector space of modular forms notes (for a Review of Riemann surfaces)
- Hecke operators and the theory of new forms
- L-functions and converse theorems
- Algebraic theory: algebraicity of eigenvalues of Hecke eigenforms, p-adic modular forms
- Applications of modular forms: Galois representation and non-abelian class field theory
Along the way, I shall review some topic such as Riemann surfaces, sheaf and algebraic geometry.
Unlike last semester, I shall upload the combined note when I think they are ready.
Here is Kindle version of William Stein's book Modular Forms: A Computational Approach that I recompiled from his TeX source code.
This time, I make all my notes in Kindle size.
