Colloquium

Speaker: Prof. Mihran Papikian (Pennsylvania State University)
Title: Graph laplacians and Drinfeld modular curves
Time: 2015-12-03 (Thu.)  15:00 - 16:00
Place: Auditorium, 6 Floor, Institute of Mathematics (NTU Campus)
Abstract: The relationship between combinatorial laplacians and automorphic forms is an active area of current research with applications to a variety of problems arising in the design of computer networks and coding theory. We will discuss a generalization of Kirchhoff's classical matrix tree theorem, and use this to give estimates, with the help of the Ramanujan-Petersson conjecture, of some invariants of Jacobian varieties of Drinfeld modular curves.
