### Multiple zeta values

Colloquium

 Speaker: Alexander Goncharov, Brown U. and MSRI Location: 693 Kerr Start time: Thu, Nov 8 2001, 4:10PM

The multiple zeta values were defined by Euler as $$\zeta(n_1, ..., n_m):= \sum_{0< k_1 < ... < k_m}\frac{1}{k_1^{n_1}... k_m^{n_m}}$$ During the last decade they appeared in many different subjects: motives, knot theory, quantization, perturbative expensions in the quantum field theory, .... We will describe some results and conjectures about the multiple zetas and, if time permits, relation with geometry of modular varieties.
