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 . WebClassification of Surfaces Richard Koch November 20, 2005 1 Introduction We are going to prove the following theorem: Theorem 1 Let S be a compact connected 2-dimensional manifold, formed from a polygon in the plane by gluing corresponding sides of the boundary together. Then S is homeomor-phic to exactly one of the following:

For each of these classes, the surfaces in the class can be parametrized by a moduli space.For most of the classes the moduli spaces are well understood, but for the class of surfaces of general type the moduli spaces seem too … philly pa to gainesville va

Webevery surface may be represented as a sphere, punctured by a finite or infinite number of discs and points, with the edges of the removed discs suitably identified. Thus we get a … Web6 de fev. de 2012 · $\begingroup$ Maybe I should have said that I take the word "surface" in the topological sense, i.e. a topological space that is separated and locally homeomorphic to $\mathbb{R}^2$. Thus, by non compact, I simply mean a surface in the above sense, that is not compact as a topological space. There is a well-known classification … Webboundary. To classify such surfaces, we can apply Richard’s theorem. Interiors ofsurfaces are homeomorphic and there exist a sequences of compact surfaces Fk such that every next contains the previous one, ∀k ≥ 1 : Fk ⊂ Fk+1. The compact connected bordered surface is topologically determined by its orientabil- philly pa to harrisburg pa
