DERIVATIONS IN SEMIGROUP ALGEBRAS
Eurasian Mathematical Journal, 2020 Summary: The main goal of this paper is to describe derivations in semigroup algebras, where the semigroup satisfies the Maltsev conditions. We prove that the derivation algebra of such semigroup algebra is embedded into the derivation algebra of some group.

On maximal subgroups of free idempotent generated semigroups [PDF]
, 2011 We prove the following results: (1) Every group is a maximal subgroup of some free idempotent generated semigroup. (2) Every finitely presented group is a maximal subgroup of some free idempotent generated semigroup arising from a finite semigroup.

Various notions of module amenability on weighted semigroup algebras
Demonstratio Mathematica, 2022 Let SS be an inverse semigroup with the set of idempotents EE. In this article, we find necessary and sufficient conditions for the weighted semigroup algebra l1(S,ω){l}^{1}\left(S,\omega ) to be module approximately amenable (contractible) and module ...

Smarandache U-liberal semigroup structure [PDF]
, 2009 In this paper, Smarandache U-liberal semigroup structure is given. It is shown that a semigroup S is Smarandache U-liberal semigroup if and only if it is a strong semilattice of some rectangular monoids. Consequently, some corresponding results on normal

Journal of Algebra, 2000 Let \(K\) be a ring with an identity and \(S\) a monoid. The paper is concerned with the homological dimension of the semigroup ring \(K[S]\) and with conditions for \(K[S]\) to be hereditary, for certain special classes of semigroups \(S\). First, if \(S\) has a finite ideal chain with factors that are non-null Rees matrix semigroups over certain ...

Generating the full transformation semigroup using order preserving mappings [PDF]
, 2003 For a linearly ordered set X we consider the relative rank of the semigroup of all order preserving mappings O-X on X modulo the full transformation semigroup Ex. In other words, we ask what is the smallest cardinality of a set A of mappings such that =

The Bergman property for semigroups [PDF]
, 2009 In this article, we study the Bergman property for semigroups and the associated notions of cofinality and strong cofinality. A large part of the paper is devoted to determining when the Bergman property, and the values of the cofinality and strong ...

A Note on Locally Inverse Semigroup Algebras
International Journal of Mathematics and Mathematical Sciences, 2008 Let R be a commutative ring and S a finite locally inverse semigroup. It is proved that the semigroup algebra R[S] is isomorphic to the direct product of Munn algebras ℳ(R[GJ],mJ,nJ;PJ) with J∈S/𝒥, where mJ is the number of ℛ-classes in J, nJ the
