• DUAL GRAPHS AND CELLULAR FOLDING OF 2-MANIFOLDS

E. M. El-Kholy, S. N. Daoud*

Abstract


In this paper we have constructed dual graphs associated with the cellular folding in a natural way. Then we obtained the condition under which we may have a successive foldings of a CW-complex into itself. We also obtained the conditions for a cartesian product and a wedge sum of two cellular foldings to be a cellular folding. These conditions are obtained in terms of the dual graphs and by using the above results we also obtained some other results.

Keywords


Cellular folding, Dual graph, Cartesian product, Wedge sum, Suspension.
