Abstract

The notion of a VnV^n-continuum was introduced by Alexandroff \cite{ps} as a generalization of the concept of nn-manifold. In this note we consider the cohomological analogue of VnV^n-continuum and prove that any strongly locally homogeneous generalized continuum XX with cohomological dimension dimGX=n\dim_G X=n is a generalized VnV^n-space with respect to the cohomological dimension dimG\dim_G. In particular, every strongly locally homogeneous continuum of covering dimension nn is a VnV^n-continuum in the sense of Alexandroff. This provides a partial answer to a question raised in \cite{tv}. An analog of the Mazurkiewicz theorem that no subset of covering dimension n2\le n-2 cuts any region of the Euclidean nn-space is also obtained for strongly locally homogeneous generalized continua XX of cohomological dimension dimGX=n\dim_G X=n.
