Some Algebraic Classification of Semiregular Hypermodules in Connection to the Radical

open access: yesJournal of Mathematics, Volume 2024, Issue 1, 2024.
We call a Krasner right S‐hypermodule A regular if each cyclic subhypermodule of A is a direct summand of A, and we also call A semiregular if every finitely generated subhypermodule of A lies above a direct summand of A. In this study, some properties of such hypermodules are achieved.

Sobolev‐Type Spaces on the Dual of the Chébli‐Trimèche Hypergroup and Applications

open access: yesAbstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014
We define and study Sobolev‐type spaces WAs,pℝ+ associated with singular second‐order differential operator on (0, ∞). Some properties are given; in particular we establish a compactness‐type imbedding result which allows a Reillich‐type theorem. Next, we introduce a generalized Weierstrass transform and, using the theory of reproducing kernels, some ...

Tur\'{a}n's inequality, nonnegative linearization and amenability properties for associated symmetric Pollaczek polynomials

open access: yes, 2020
An elegant and fruitful way to bring harmonic analysis into the theory of orthogonal polynomials and special functions, or to associate certain Banach algebras with orthogonal polynomials satisfying a specific but frequently satisfied nonnegative ...

Reiter’s condition P1 and approximate identities for polynomial hypergroups.

open access: yes, 2004
Let K be a commutative hypergroup with the Haar measure . In the present paper we investigate whether the maximal ideals in L1ðK; Þ have bounded approximate identities.

On positive definite and stationary sequences with respect to polynomial hypergroups.

open access: yes, 2011
We study bounded positive definite double sequences which are stationary with respect to a polynomial hypergroup structure generated by . Connected with bounded positive definite and Rn-stationary double sequences is an Rn-stationary sequence of elements

About a decomposition of the group Zpq, where p and q are distinct odd primes

open access: yes, 2010
In this paper we are interested in finding a partition of Zn such that the component sets satisfy two properties: the first one says that the double of each element of every set is congruent modulo n with the consecutive element of the same set; the ...

(Intuitionistic) Fuzzy Grade of a Hypergroupoid: A Survey of Some Recent Researches

open access: yesRatio Mathematica, 2012
This paper aims to present a short survey on two numerical functions determined by a hypergroupoid, called the fuzzy grade and the intuitionistic fuzzy grade of a hypergroupoid.

Limit theorems for random walks on the double coset spaces U(n)∥U(n − 1) for n → ∞

open access: yes, 1995
Let (Yjn)j⩾0 be an isotropic random walk on the homogeneous space U(n)U(n − 1) (n⩾2) and πn the canonical projection from U(n)U(n − 1) onto the double coset hypergroup U(n)∥U(n − 1) which will be identified with the unit disk D ⊂ C.

Semihypergroups and regular equivalences

open access: yes, 1980
We determine a new structure of semi-hypergroup on the quotient, modulus a regular equivalence, of a semi-hypergroup and we analize its properties. Moreover we introduce and we examine closely the concept of a relative semi-hypergroup to a relation R, a ...
