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 ...

Hv-module of functions over Hv-ring of arithmetics and it’s fundamental module

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
After introducing the definition of hypergroups by Marty, the study of hyperstructures and its connections with other fields has been of great importance. In this paper, we continue the investigation between hyperstructure theory and number theory.

(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.

On the local time of random walks associated with Gegenbauer polynomials

open access: yes, 2010
The local time of random walks associated with Gegenbauer polynomials $P_n^{(\alpha)}(x),\ x\in [-1,1]$ is studied in the recurrent case: $\alpha\in\ [-\frac{1}{2},0]$.

Mehler Semigroups, Ornstein-Uhlenbeck processes and background driving Lévy processes on locally compact groups and on hypergroups [PDF]

open access: yes, 2009
For finite dimensional vector spaces it is well-known that there exists a 1-1-correspondence between distributions of Ornstein-Uhlenbeck type processes (w.r.t. a fixed group of automorphisms) and (background driving) Lévy processes.

A family of 0-simple semihypergroups related to sequence A000070 [PDF]

open access: yes, 2016
For any integer n 65 2, let R_0(n + 1) be the class of 0-semihypergroups H of size n + 1 such that {y} 86 xy 86 {0, y} for all x, y 08 H - {0}, all subsemihypergroups K 86 H are 0-simple and, when |K| 65 3, the fundamental relation \u3b2_K is not ...

Nonnegative and strictly positive linearization of Jacobi and generalized Chebyshev polynomials

open access: yes, 2019
In the theory of orthogonal polynomials, as well as in its intersection with harmonic analysis, it is an important problem to decide whether a given orthogonal polynomial sequence $(P_n(x))_{n\in\mathbb{N}_0}$ satisfies nonnegative linearization of ...

From monoids to hyperstructures: in search of an absolute arithmetic

open access: yes, 2010
We show that the trace formula interpretation of the explicit formulas expresses the counting function N(q) of the hypothetical curve C associated to the Riemann zeta function, as an intersection number involving the scaling action on the adele class ...

q-Krawtchouk polynomials as spherical functions on the Hecke algebra of type B

open access: yes, 1996
The generic Hecke algebra for the hyperoctahedral group, i.e. the Weyl group of type B, contains the generic Hecke algebra for the symmetric group, i.e. the Weyl group of type A, as a subalgebra.
