Abstract

A topological space AA is said to be compatible with a set Σ\Sigma of equations (involving operation symbols FtF_t) iff there are continuous operations Ft\overline F_t identically satisfying Σ\Sigma on AA. The paper's main focus is on the compatibility relation for AA a finite simplicial complex. We review and extend the known compatibilities and incompatibilities in this context. Many such spaces are compatible with no non-trivial Σ\Sigma. The paper concludes with open questions. For example, if AA is compatible with Σ\Sigma, can this fact be deduced from the compatibility of AA with some Γ\Gamma that involves only ternary operations? If AA is compatible with Σ\Sigma, can the operations Ft\overline F_t be chosen as piecewise multilinear? Is the compatibility relation (between finite Σ\Sigma and finite complexes AA) algorithmic? For AA a one-simplex (i.e., a closed real interval), is there some simple characterization of the set of all Σ\Sigma compatible with AA?
