La conjecture sur les classes sphériques affirme que les classes détectées par l'invariant de Hopf et l'invariant de Kervaire sont les seules dans dans l'image de l'homomorphisme de Hurewicz. L'homomorphisme de Lannes–Zarati est l'application correspondant au gradué (pour une certaine filtration) de l'homomorphisme de Hurewicz. La version algébrique de la conjecture prédit que le s-ième homomorphisme de Lannes–Zarati s'annule en tout degré positif pour . Dans cette note, nous démontrons la conjecture pour le cinquième homomorphisme de Lannes–Zarati.
The conjecture on spherical classes states that the Hopf invariant one and the Kervaire invariant one classes are the only elements in belonging to the image of the Hurewicz homomorphism. The Lannes–Zarati homomorphism is a map that corresponds to an associated graded (with a certain filtration) of the Hurewicz map. The algebraic version of the conjecture predicts that the s-th Lannes–Zarati homomorphism vanishes in any positive stems for . In the article, we prove the conjecture for the fifth Lannes–Zarati homomorphism.
