Dr (Smt). S. N. BANASODE, SEEMA B PATIL*, JAYASHREE.S. RADDER

Abstract


Up to homeomorphism all compact simple oriented close surfaces are either a sphere S2 or S2 with g handles, g = 1, 2, 3, …..Called the genius of the surface. In this paper we observe that there is a nice characterization come from the topology at the surface and with the classification theme for contractibility. These are some hard results.


Keywords


Contractibility, Orientable surface, S2 with g handles.
