Stably Definable Classes of Theories
E. A. Palyutin Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences
Abstract:
A question is studied as to which properties (classes) of elementary theories can be defined via generalized stability. We present a topological account of such classes. It is stated that some well-known classes of theories, such as strongly minimal, $o$-minimal, simple, etc., are stably definable, whereas, for instance, countably categorical, almost strongly minimal, $\omega$-stable ones, are not.
Keywords:
elementary theory, stably definable class.
