Functoriality of the standard resolution of the Cartesian product of a compactum and a polyhedron
چکیده انگلیسی

In a previous paper the author has associated with every inverse system of compact Hausdorff spaces X with limit X and every simplicial complex K (possibly infinite) with geometric realization P=|K| a resolution RK(X) of X×P, which consists of paracompact spaces. If X consists of compact polyhedra, then RK(X) consists of spaces having the homotopy type of polyhedra. In the present paper it is proved that this construction is functorial. One of the consequences is the existence of a functor from the strong shape category of compact Hausdorff spaces X to the shape category of spaces, which maps X to the Cartesian product X×P. Another consequence is the theorem which asserts that, for compact Hausdorff spaces X, X′, such that X is strong shape dominated by X′ and the Cartesian product X′×P is a direct product in Sh(Top), then also X×P is a direct product in the shape category Sh(Top).
