Equivariant maps of joins of finite G-sets and an application to critical point theory
A lower estimate is proved for the number of critical orbits and critical values of a G-invariant C¹ function , where G is a finite nontrivial group acting freely and orthogonally on . Neither Morse theory nor the minimax method is applied. The proofs are based on a general version of Borsuk’s Antipodal Theorem for equivariant maps of joins of G-sets.

Espaces différentiables singuliers et corps de nombres algébriques
On étudie quelques propriétés différentiables de l’espace , quotient du tore par un hyperplan irrationnel . On montre d’une part que le groupe des composantes connexes de Diff est isomorphe au groupe des unités de l’algèbre des matrices à coefficients entiers qui stabilisent , et d’autre part que ce groupe est isomorphe au groupe des unités d’un ordre d’un corps de nombres algébriques.
