FORKING AND SUPERSTABILITY IN TAME AECS [PDF]
The Journal of Symbolic Logic, 2016 AbstractWe prove that any tame abstract elementary class categorical in a suitable cardinal has an eventually global good frame: a forking-like notion defined on all types of single elements. This gives the first known general construction of a good frame in ZFC.

On the superstability of the generalized orthogonality equation in Euclidean spaces [PDF]
, 1994 We consider a class of approximate solutions of the generalized orthogonality equation in ℝn (n≥2). We prove that this class coincides with the class of solutions of the equation, i.e., the superstability of the generalized orthogonality equation ...

Stability and Superstability of Generalized (, )-Derivations in Non-Archimedean Algebras: Fixed Point Theorem via the Additive Cauchy Functional Equation [PDF]
, 2011 Let be an algebra, and let , be ring automorphisms of . An additive mapping ∶→ is called a (,)-derivation if ()=()()+()() for all ,∈. Moreover, an additive mapping ∶→ is said to be a generalized (,)-derivation if there exists a (,)-derivation ∶→ such ...

On Stability of a Functional Equation Connected with the Reynolds Operator
Journal of Inequalities and Applications, 2007 Let (X,∘) be an Abelain semigroup, g:X→X, and let K be either ℠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.

Superstability of approximate cosine type functions on the monoid ℝ² [PDF]
, 2012 In this paper, we study the superstability problem for the cosine type functional equation f(x₁x₂, x₁y₂ + x₂y₁) + f(x₁x₂, y₁x₂ ‒ x₁y₂) = 2 f(x₁, y₁) f(x₂, y₂) on the commutative monoid (ℝ²,X).

Superstability in abstract elementary classes
, 2018 We prove that several definitions of superstability in abstract elementary classes (AECs) are equivalent under the assumption that the class is stable, tame, has amalgamation, joint embedding, and arbitrarily large models.
