A compact minimal space $Y$ such that its square $Y\times Y$ is not minimal
Abstract
The following well known open problem is answered in the negative: Given two compact spaces and that admit minimal homeomorphisms, must the Cartesian product admit a minimal homeomorphism as well? A key element of our construction is an inverse limit approach inspired by combination of a technique of Aarts & Oversteegen and the construction of Slovak spaces by Downarowicz & Snoha & Tywoniuk. This approach allows us also to prove the following result. Let be a continuous, aperiodic minimal flow on the compact, finite--dimensional metric space . Then there is a generic choice of parameters , such that the homeomorphism admits a noninvertible minimal map as an almost 1-1 extension.

Theorem 3.6 is added, where it is shown that minimal spaces without minimal squares can appear as minimal sets of torus homeomorphisms homotopic to the identity
