        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.
