WebFirst edition. A Guide to the Classification Theorem for Compact Surfaces is a textbook in topology, on the classification of two-dimensional surfaces. It was written by Jean … Web2.2 Non-orientable surfaces . The simplest non-orientable surface is the real projective plane: for the history of the discovery of this interesting manifold see the page Projective plane: a history.. All non-orientable surfaces are homeomorphic to the connected sum of real projective planes and and so for all we define , to be the -fold connected sum of .
