WebIn mathematics, the Enriques–Kodaira classification is a classification of compact complex surfaces into ten classes. 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 …

Let Σg denote a closed oriented genus g surface. Theorem 1. Let X be a closed oriented surface. Then X ∼= Σ g for some g ≥ 0. Remark. It is an easy exercise to extend this proof to deal with non-orientable surfaces and surfaces with boundary. Proof of Theorem 1. inauthor: roger d. blackwell

WebThe second revison contains a conjecture (that I am 99% sure of) describing the complete answer to this question. The first point is that the classification of symplectic surfaces can not be simpler than the classification of surfaces up to a diffeo. And the classification up to a diffeo of non-compact surfaces is quite a delicate subject. 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-
