|Joint IAS-PU Number Theory Seminar|
|Topic:||Multiple Zeta Values|
|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.
