The Hilali conjecture on product of spaces

Algebraic Topology 2019-12-10 v1

Abstract

The Hilali conjecture claims that a simply connected rationally elliptic space XX satisfies the inequality dim(π(X)Q)dimH(X;Q)\operatorname{dim} (\pi_*(X)\otimes \mathbb Q ) \leqq \operatorname{dim} H_*(X;\mathbb Q ). In this paper we show that for any such space XX there exists a positive integer n0n_0 such that for any nn0n \geqq n_0 the \emph{strict inequality} dim(π(Xn)Q)<dimH(Xn;Q)\operatorname{dim} (\pi_*(X^n)\otimes \mathbb Q ) < \operatorname{dim} H_*(X^n;\mathbb Q ) holds, where XnX^{n} is the product of nn copies of XX.
