Arithmetic Study Group: Multiple zeta values and the geometry of moduli spaces of curves
8 November 2007 14:15 in CM219
A.B. Goncharov and Manin have shown that the moduli spaces of curves of genus 0 with n marked points are natural spaces in which one can find multiple zeta values as periods and in which one can build a motivic avatar (over $\Z$) of the multiple zeta values. In this talk, we will describe the geometry of those spaces needed in order to sketch a proof of the main result of Goncharov and Manin on the algebraic aspect of their work. The motivic part of the article will be discussed in a later talk.
