Several properties of complexity classes and sets associated with them are studied. An open problem, the enumerability of complexity classes, is settled by exhibition of a measure with some nonenumerable classes. Classes for natural measures are found to occupy the same isomorphism type; and a crite

A class K of structures is controlled if for all cardinals , the relation of L ∞; -equivalence partitions K into a set of equivalence classes (as opposed to a proper class). We prove that no pseudo-elementary class with the independence property is controlled. By contrast, there is a pseudo-elementa
