Résumé
Abstract

Soit $f : S^{4 n - 2} \to S^{2 n}$ une application continue entre les sphères de dimensions respectives $4 n - 2$ et $2 n$ pour $n > 4$ . Nous démontrons que, si la paire $(f, f)$ est déformable en une paire libre de coïncidences, alors elle n'est pas déformable par petites déformations si et seulement si $n = 2^{j}$ , $j ⩾ 3$ , et l'invariant de Kervaire de la classe d'homotopie $[f] \in π_{4 n - 2} (S^{2 n})$ est 1. Cette dernière condition est équivalente à une forme forte du problème de Kervaire.

Let $f : S^{4 n - 2} \to S^{2 n}$ be a map between spheres of dimensions $4 n - 2$ and $2 n$ with $n > 4$ . We show that the existence of such a map satisfying the property that the pair $(f, f) : S^{4 n - 2} \to S^{2 n}$ can be deformed to a coincidence free pair but cannot be deformed to coincidence free by small deformation is equivalent to the Strong Kervaire Invariant One Problem, i.e., the existence of an element of order 2 with Kervaire invariant one in the stable homotopy group $π_{2 n - 2}^{s}$ .
