The sphere, torus, Klein bottle, and the projective plane are the classical examples of orientable and non-orientable surfaces. As with much of mathematics, it is natural to ask the question: are these all possible surfaces, or, more generally, can we classify all … 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 … aries january 2023

WebAmerican Mathematical Society :: Homepage 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.
