Some L2 properties of semigroups of measures on Lie groups [PDF]

open access: yes, 2009
We investigate the induced action of convolution semigroups of probability measures on Lie groups on the L 2-space of Haar measure. Necessary and sufficient conditions are given for the infinitesimal generator to be self-adjoint and the associated ...

A Decomposition‐Based Unified Evolutionary Algorithm for Many‐Objective Problems Using Particle Swarm Optimization

open access: yesMathematical Problems in Engineering, Volume 2016, Issue 1, 2016., 2016
Evolutionary algorithms have proved to be efficient approaches in pursuing optimum solutions of multiobjective optimization problems with the number of objectives equal to or less than three. However, the searching performance degenerates in high‐dimensional objective optimizations.

Uncertainty Principles for the Dunkl‐Wigner Transforms

open access: yesJournal of Operators, Volume 2016, Issue 1, 2016., 2016
We prove a version of Heisenberg‐type uncertainty principle for the Dunkl‐Wigner transform of magnitude s > 0; and we deduce a local uncertainty principle for this transform.

Continuous Association Schemes and Hypergroups

open access: yes, 2017
Classical finite association schemes lead to a finite-dimensional algebras which are generated by finitely many stochastic matrices. Moreover, there exist associated finite hypergroups.

Ordered Left Almost ⋇‐Semihypergroups Based on Fuzzy Sets

open access: yesJournal of Mathematics, Volume 2024, Issue 1, 2024.
The concept of an involution or anti‐involution is a self‐inverse linear mapping that plays a prominent role in the theory of algebraic structures, particularly rings, hyperrings, ordered semigroups, and ordered semihypergroups. Nowadays, the study of involutions in ordered hyperstructures is a particular area of research in the field of hyperstructure

Some Generalized Forms of Fuzzy Interval Valued Hyperideals in a Hyperring

open access: yesJournal of Applied Mathematics, Volume 2014, Issue 1, 2014., 2014
Some generalized forms of the hyperideals of a hyperring in the paper of Zhan et al. (2008) will be given. As a generalization of the interval valued (α, β)‐fuzzy hyperideals of a hyperring with α, β ∈ {∈, q, ∈∧q, ∈∨q} and α ≠ ∈∧q, the notion of generalized interval valued (α, β)‐fuzzy hyperideals of a hyperring is also introduced. Special attention is

Amenability properties of the central Fourier algebra of a compact group

open access: yes, 2015
We let the central Fourier algebra, ZA(G), be the subalgebra of functions u in the Fourier algebra A(G) of a compact group, for which u(xyx^{-1})=u(y) for all x,y in G.

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.
