Multiple Zeta Values

Joint IAS-PU Number Theory Seminar
Topic:Multiple Zeta Values
Speaker:Francis Brown
Affiliation:CNRS/Institut de Math. de Jussieu, Paris
Date:Thursday, April 19
Time/Room:4:30pm - 5:30pm/S-101

I will report on some recent work on multiple zeta values. I will sketch the definition of motivic multiple zeta values, which can be viewed as a prototype of a Galois theory for certain transcendental numbers, and then explain how they were used to prove a conjecture due to Hoffman giving a generating family for multiple zeta values, and a conjecture of Deligne and Ihara on the fundamental group of the projective line minus 3 points.
