"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 … " - On the classification of non-compact surfaces
