C-spaces and simplicial complexes
Given a class
of simplicial complexes G, we introduce the notion of a
-C-space. In the definition of a C-space, open disjoint families vi refine coverings ui. The nerves of these families are zero-dimensional complexes. In our definition, the nerve of a family vi must embed in the complex Gi of the class
. We give a complete characterization of bicompact
-C-spaces.
