Date：2011-12-06 (14:30--15:30, 16:00-17:00)

Venue：Room 29 at Quan-Zhai (全斋), New location for BICMR, Peking University

Speaker：Spencer Bloch (University of Chicago)

Abstract: I will explain an elementary way to think of the motive associated to the fundamental group of an algebraic variety and related constructions. A generalization of iterated integrals associates to any graph periods which, in special cases, yield generalizations of multiple zeta values.
