We give in this paper a description of a new extension of the concept of contractible spaces to arbitrary topological spaces analogous to the notion of spaces of trivial shape. We shall use multi-valued functions with smaller and smaller images of points. Our notion is modeled on the property that every map from a contractible space is null-homotopic.
