Karcher Special Lecture
Periods, L-functions and a small step beyond endoscopy
Yiannis Sakellaridis, Rutgers University Newark

Tea will be served at 3:30pm in PHSC 424.
I will describe a conjectural picture about how certain periods of automorphic forms are related to L-functions. Then I will outline a novel approach to the relative trace formula which gives a new proof of a special case of these conjectures: Waldspurger periods over tori for PGL(2) and its inner forms.
