Abstract
It is established that the dihedral homologies of involutive A∞A_{\infty }-algebras are homotopically invariant with respect to the homotopy equivalences of involutive A∞A_{\infty }-algebras. As a consequence, it is shown that over any field, the dihedral homologies of a topological space are isomorphic to the dihedral homologies of the involutive A∞A_{\infty }-algebra of homologies for the simplicial group of Kan loops of the original topological space.
