Sur l'application de Quillen pour la cohomologie modulo 2 de certains groupes finis

Abstract: Let $G$ be a finite group. In a famous article, Quillen describes an $\mathrm{F}$-isomorphism between commutative $\mathbb{N}$-graded $\mathbb{F}{2}$-algebras $$\mathrm{q}{G}:\mathrm{H}^{*}(G;\mathbb{F}_{2})\to\mathrm{L}(G)\ ,$$ with $\mathrm{L}(G)$ defined in terms of the elementary abelian $2$-groups contained in $G$. We show that $\mathrm{q}_{G}$ is in fact an actual isomorphism for three families of finite groups: symmetric groups, alternating groups and finite Coxeter groups.
