Nous introduisons et etudions une notion generale de foncteur polynomial depuis une petite categorie monoidale symetrique dont l'unite est objet initial, et donnons un resultat de classification des foncteurs polynomiaux de degre au plus n modulo ceu

On calcule dans cet article l'homologie stable des groupes orthogonaux et symplectiques sur un corps fini k a coefficients tordus par un endofoncteur usuel F des k-espaces vectoriels (puissance exterieure, symetrique, divisee...), c'est-a-dire, pour

In this paper, we define the functor category F quad associated to F 2 -vector spaces equipped with a quadratic form. We show the existence of a fully faithful, exact functor ι : F → F quad , which preserves simple objects, where F is the category

We study in this article stable homology of automorphism groups of free groups with coefficients twisted by a poynomial functor. We show that this homology is zero for a reduced covariant polynomial functor. For a reduced contravariant functor, we co

We prove that Leibniz homology of Lie algebras can be described as functor homology in the category of linear functors from a category associated to the Lie operad.

In this paper, we give a description of polynomial functors from (finitely generated free) groups to abelian groups in terms of non-linear Mackey functors generalizing those given in a paper of Baues-Dreckmann-Franjou-Pirashvili published in 2001. Th

We study polynomial functors of degree 2, called quadratic, with values in the category of abelian groups $Ab$, and whose source category is an arbitrary category $\C$ with null object such that all objects are colimits of copies of a generating obje
