Résumé : Renormalization of multiple zeta values for negative integers. Using Connes and Kreimer renormalization, we will show how to extend multpiple zeta functions to every complex argument so that the "quasi-abattage" relations are preserved. The values obtained for negative integers are rational. We will discuss a multi-dimensional analogue. Common work with Sylvie Paycha.
