Stability of additive functional equation on discrete quantum semigroups [PDF]

Sahand Communications in Mathematical Analysis, 2017
We construct  a noncommutative analog of additive functional equations on discrete quantum semigroups and show that this noncommutative functional equation has Hyers-Ulam stability on amenable discrete quantum semigroups.

Multiplicative Perturbations of Convoluted C-Cosine Functions and Convoluted C-Semigroups

Journal of Function Spaces and Applications, 2013
We obtain the multiplicative perturbation theorems for convoluted C-cosine functions (resp., convoluted C-semigroups) and n-times integrated C-cosine functions (resp., n-times integrated C-semigroups) for n∈ℕ.

Quasi-Distribution Semigroups and Integrated Semigroups

Journal of Functional Analysis, 1997
The author extends the notion of generator of distribution semigroups on Banach spaces to non-densely defined operators. He also introduces a functional calculus for these operators and characterizes integrated semigroups in terms of this functional calculus.

On some classes of generalized numerical semigroups

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
A generalized numerical semigroup is a submonoid of ℕd with finite complement in it. In this work we study some properties of three different classes of generalized numerical semigroups defined starting from numerical semigroups.

THE DUALITY OF THE L?-REPRESENTATION ALGEBRA ?(S ) OF A FOUNDATION SEMIGROUP S AND FUNCTION ALGEBRAS [PDF]

Journal of Sciences, Islamic Republic of Iran, 2000
In the present paper for a large family of topological semigroups, namely foundation semigroups, for which topological groups and discrete semigroups are elementary examples, it is shown that ?(S) is the dual of a function algebra.

Properties of semigroups of elementary types of model classes

Қарағанды университетінің хабаршысы. Математика сериясы
The study of classes of first-order countable language models and their properties is an important direction in model theory. Of particular interest are axiomatizable classes of models (varieties, quasivarieties, finitely axiomatizable classes ...
