Solly Parenti 
RankinSelberg Lfunctions 
What do you get when you cross an Eisenstein series with a cuspform? An Lfunction! Since there's no modular forms course this semester, I will try to squeeze in an entire semester's course on modular forms during the first part of this talk, and then I'll explain the RankinSelberg method of establishing analytic continuation of certain Lfunctions.

Wanlin Li 
Intersection Theory on Modular Curves 
My talk is based on the paper by François Charles with title "FROBENIUS DISTRIBUTION FOR PAIRS OF ELLIPTIC CURVES AND EXCEPTIONAL ISOGENIES". I will talk about the main theorem and give some intuition and heuristic behind it. I will also give a sketch of the proof.

Dongxi Ye 
Modular Forms, Borcherds Lifting and GrossZagier Type CM Value Formulas 
During the course of past decades, modular forms and Borcherds lifting have been playing an increasingly central role in number theory. In this talk, I will partially justify these by discussing some recent progress on some topics in number theory, such as representations by quadratic forms and GrossZagier type CM value formulas.

Ewan Dalby 
The Cuspidal Rational Torsion Subgroup of J_0(p) 
I will define the cuspidal rational torsion subgroup for the Jacobian of the modular curve J_0(N) and try to convince you that in the case of J_0(p) it is cyclic of order (p1)/gcd(p1,12).
