Coordinatization in Superstable Theories. II [PDF]

open access: yesTransactions of the American Mathematical Society, 1988
In this paper we prove Theorem A. Suppose that T T is superstable and U ( a / A ) = α + 1 U(a/A) = \alpha + 1 , for some α \alpha . Then in T eq

On Stability of a Functional Equation Connected with the Reynolds Operator

open access: yesJournal of Inequalities and Applications, 2007
Let (X,∘) be an Abelain semigroup, g:X→X, and let K be either ℝ or ℂ. We prove superstability of the functional equation f(x∘g(y))=f(x)f(y) in the class of functions f:X→K.

On the Superstability of the Pexider Type Trigonometric Functional Equation

open access: yesJournal of Inequalities and Applications, 2010
We will investigate the superstability of the (hyperbolic) trigonometric functional equation from the following functional equations: f(x+y)±g(x−y)=λf(x)g(y) andf(x+y)±g(x−y)=λg(x)f(y), which can be considered ...

An estimation for the generalized ternary ring homomorphism on non-Archimedean ternary Banach algebras

open access: yesMiskolc Mathematical Notes
In this paper, we introduce the notion of the generalized ternary ring homomorphism on non-Archimedean ternary Banach algebras. Using fixed point methods, we prove the superstability and generalized Hyers-Ulam stability of generalized ternary ring ...

Survey on Recent Ulam Stability Results Concerning Derivations

open access: yesJournal of Function Spaces, 2016
This is a survey presenting the most significant results concerning approximate (generalized) derivations, motivated by the notions of Ulam and Hyers-Ulam stability.

Superstable fields and groups

open access: yesAnnals of Mathematical Logic, 1980
AbstractWe prove an indecomposability theorem for connected stable groups. Using this theorem we prove that all infinite superstable fields are algebraically closed, and we extend known results for ω-stable groups of Morley rank at most 3 to the corresponding class of superstable groups (Note: The logical notion of stability is unrelated to the notion ...
