A Geometric Decomposition of Spaces into Cells of Different Types

##
Gabriel Minian and Miguel Ottina

We develop the theory of CW(A)-complexes, which generalizes the classical theory of CW-complexes, keeping
the geometric intuition of J.H.C. Whitehead's original theory. We obtain this way generalizations of classical results, such
as Whitehead Theorem, which allow a deeper insight in the homotopy properties of these spaces.
