Abstract: 
“Dimension formula of Modular forms through Arthur Trace formula”


Trace formula is an important tool in modern number theory. In this talk,  we will use trace formula to obtain the dimension formula of modular forms. It is a special case of Eichler-Selberg trace formula, which give an explicit formula for the trace of Hecke operators.
 
(1) representation of SL_2(R): I will discuss (g,K) module, subrepresentation theorem, classification of (g,K) module of SL_2(R), discrete series, matrix coefficient, etc.

(2) modular forms and L^2 space: I will dicuss how modular from can be embeded in L^2 (SL2_(Z) \ SL_2(R)). The spectral decomposition of the L^2
space. And sketch the idea of obtaining the dimension formula.


(3) trace formula and detail computation: we will derive the trace formula, and give explcit calculation of the trace formula.
