Annals of Pure and Applied Logic, 1986 This paper is an important contribution to the theory of stable groups. Powerful use is made of Lascar's U-rank, enabling new results as well as generalizations of the finite rank theory to be proved for arbitrary superstable groups. From now on let G denote a (saturated) superstable group (possibly with additional structure). A fundamental observation

Superstability, noetherian rings and pure-semisimple rings [PDF]
Annals of Pure and Applied Logic, 2019 We uncover a connection between the model-theoretic notion of superstability and that of noetherian rings and pure-semisimple rings. We characterize noetherian rings via superstability of the class of left modules with embeddings.

Nearly Ring Homomorphisms and Nearly Ring Derivations on Non-Archimedean Banach Algebras
Abstract and Applied Analysis, 2010 We prove the generalized Hyers-Ulam stability of homomorphisms and derivations on non-Archimedean Banach algebras. Moreover, we prove the superstability of homomorphisms on unital non-Archimedean Banach algebras and we investigate the superstability of ...

Stability and Superstability of Ring Homomorphisms on Non-Archimedean Banach Algebras
Abstract and Applied Analysis, 2011 Using fixed point methods, we prove the superstability and generalized Hyers-Ulam stability of ring homomorphisms on non-Archimedean Banach algebras. Moreover, we investigate the superstability of ring homomorphisms in non-Archimedean Banach algebras ...

Isogeny in superstable groups [PDF]
Archive for Mathematical Logic, 2014 We study and develop a notion of isogeny for superstable groups. We prove several fundamental properties of the notion and then use it to formulate and prove uniqueness results. Connections to existing model theoretic notions are explained.

Superstable Theories and Representation
Sarajevo Journal of Mathematics, 2022 In this paper we give an additional characterizations of the first order complete superstable theories, in terms of an external property called representation. In the sense of the representation property, the mentioned class of first-order theories can be regarded as "not very complicated".

On superstability in the class of flat modules and perfect rings [PDF]
, 2019 We obtain a characterization of left perfect rings via superstability of the class of flat left modules with pure embeddings. $\mathbf{Theorem.}$ For a ring $R$ the following are equivalent. - $R$ is left perfect.

Approximately Ternary Homomorphisms on C*-Ternary Algebras
Abstract and Applied Analysis, 2013 Gordji et al. established the Hyers-Ulam stability and the superstability of C*-ternary homomorphisms and C*-ternary derivations on C*-ternary algebras, associated with the following functional equation: fx2-x1/3+fx1-3x3/3+f3x1+3x3-x2/3=fx1, by the ...

Superstability from categoricity in abstract elementary classes [PDF]
Annals of Pure and Applied Logic, 2016 Starting from an abstract elementary class with no maximal models, Shelah and Villaveces have shown (assuming instances of diamond) that categoricity implies a superstability-like property for nonsplitting, a particular notion of independence.
