چکیده
In this note we state some results concerning the perturbation problem of strongly continuous semigroups on a Banach space X and provide some new characterizations of the uniformly continuous semigroups on X.

متن کاملp-Analog of the Semigroup Fourier-Steiltjes Algebras
In this paper we define the $p$-analog of the restericted reperesentations and also the $p$-analog of the Fourier--Stieltjes algebras on the inverse semigroups . We improve some results about Herz algebras on Clifford semigroups. At the end of this paper we give the necessary and sufficient condition for amenability of these algebras on Clifford semigroups.
متن کاملSome results on Noetherian semigroup
In this paper we study some results on Noetherian semigroups. We show that if $S_S$ is an strongly faithful $S$-act and $S$ is a duo weakly Noetherian, then we have the following.
متن کاملUNIVERSAL COMPACTIFICATIONS OF TRANSFORMATION SEMIGROUPS
We extend the notion of semigroup compactification to the class of transformation semigroups, and determine the compactifications which are universal with respect to some topological properties.
متن کاملSome properties of a class of polyhedral semigroups based upon the subword reversing method
In this paper a certain class of polyhedral semigroups which has a presentation $$ is examined. The completeness of the presentation and solvability of word problem of this class of semigroups is determined. Moreover the combinatorial distance between two words is determined.
متن کاملRegular ordered semigroups in terms of fuzzy subsets
In this paper we extend some results concerning ideals of left regular and intra-regular ordered semigroups to fuzzy ordered semigroups. A theory of fuzzy sets on ordered groupoids and ordered semigroups can be developed. Some results on ordered groupoidssemigroups have been already given by the same authors. The aim of writing this paper is to show the way we pass from the theory of ordered se...
