En 2001, Kedlaya introduisit un algorithme permettant de calculer la fonction zêta d’une courbe hyperelliptique sur un corps fini de caractéristique impaire. Cet algorithme emploie des méthodes p-adiques avec la cohomologie de Monsky-Washnitzer. Dans cet exposé, on présentera un travail

Let \(G\) be a compact group with two given subgroups \(H\) and \(K\). Let \(\pi\) be an irreducible representation of \(G\) such that its space of \(H\)-invariant vectors as well as the space of \(K\)-invariant vectors are both one dimensional.

Exceptionnellement à 15h. Abstract: Feynman integrals, besides being useful in perturbative quantum field theories, are also a source of interesting transcendental functions such as multiple polylogarithms (or even more complicated and poorly understood classes of functions).  Still, at present we
