In the framework of the project "Clay mathematical lectures" (see the home page of Clay Mathematical Institute), Pierre Deligne will deliver a cycle of three lectures at the IUM.

**Title:**- Report on Multizeta Values
**Schedule:**- Thursday, April 25, 2002, 3:40pm
- Friday, April 26, 5:00pm
- Monday, April 29, 5:00pm

**Abstract:**- Multizeta values were first considered by Euler, who proved among other identities that $\zeta(2,1):=\sum_{n>m}1/n^2m$ equals $\zeta(3):=\sum 1/n^3$. More recently, they appeared as the coefficients of Drinfeld associator. They encode the mixed Hodge structure of the fundamental group (made unipotent) of ${\mathbb P}^1-\{0,1,\infty\}$. This makes the philosophy -- and theory -- of motives applicable.
