Bipolar-Valued Fuzzy Ideals in LA-semigroups
LA-semigroups Bipolar-valued fuzzy LA-subsemigroups Bipolar-valued fuzzy left (right) ideals
2011/9/19
Abstract: In this paper, the notion of bipolar-valued fuzzy LA-subsemigroups is introduced and also some properties of bipolar-valued fuzzy left (right, bi-, interior) ideals of LA-semigroups has been...
Bicyclic semigroups of left I-quotients
bicyclic semigroup bisimple inverse w-semigroup I-quotients Iorder
2011/9/13
Abstract: In this article we study left I-orders in the bicyclic monoid $\mathcal{B}$. We give necessary and sufficient conditions for a subsemigroup of $\mathcal{B}$ to be a left I-oreder in $\mathca...

2011/8/29
Abstract: In this paper we discuss various aspects of the problem of determining the minimal dimension of an injective linear representation of a finite semigroup over a field. We outline some general...
Ideals in intra-regular left almost semigroups
LA-semigroups intra-regular LA-semigroups and (1, 2)-ideals
2011/2/28
In this paper, we have introduced the notion of (1, 2)-ideal in an LA-semigroup and shown that (1, 2)-ideal and two-sided ideal coincide in an intra-regular LA-semigroup.
Exponential Convergence Rates of Second Quantization Semigroups and Applications
Convergence rate tail norm entropy second quantization L´ evy processes
2011/2/28
Exponential convergence rates in the L2-tail norm and entropy are characterized for the second quantization semigroups by using the corresponding base Dirichlet form. This supplements the well known r...
We introduce a new class of semigroups arising from a restricted class of asynchronous automata. We call these semigroups "expanding automaton semigroups." We show that the class of synchronous autom...
Logarithmic Sobolev inequality for diffusion semigroups
Logarithmic Sobolev inequality Poincar´ e inequality Ornstein-Uhlenbeck semigroup
2010/12/8
Through the main example of the Ornstein-Uhlenbeck semigroup, the Bakry-Emery criterion is presented as a main tool to get functional inequalities as Poincar´e or logarithmic Sobolev inequalitie...

Subgroups free idempotent generated semigroups: full linear monoid
2010/12/14
We develop some new topological tools to study maximal subgroups of free idempotent generated semigroups. As an application,we show that the rank 1 component of the free idempotent generated semigroup...
Convergence of semigroups of measures on a Lie group
Semigroups of measures dissipative distributions Hunt theory Lie groups
2010/12/9
A theorem of Siebert asserts that if μn(t) are semigroups of probability measures on a Lie group G, and Pn are the corresponding generating functionals,then μn(t).

2010/12/6
A semigroup variety is said to be a Rees-Sushkevich variety if it is contained in a periodic variety generated by 0-simple semigroups. S. I. Kublanovsky has proven that a variety V is a Rees—Sushkevic...

We show that many important varieties and sets of varieties of semigroups may be defined by relatively simple and transparent first-order formulas in the lattice of all semigroup varieties.

We study in fairly general measure spaces $(X,\mu)$ the (non-linear) potential theory of $L^p$ sub-Markovian semigroups which are given by kernels having a density with respect to the underlying measu...
Skew Pairs of Idempotents in Transformation Semigroups

2007/12/11
An ordered pair $(e,f)$ of idempotents of a regular semigroup is called a {\it skew pair} if $ef$ is not idempotent whereas $fe$ is idempotent. We have shown previously that there are four distinct ty...
