The first order cyclic cohomology group of some commutative semigroup algebras
مجلة جامعة الزيتونة, 2023 In this paper, we shall calculate the first order cyclic cohomology group ℋ???? 1(ℓ 1(????),ℓ ∞(????)) where ???? is a certain commutative, 0-cancellative, ???????????? ♯-semigroup.

Constructions of positive commutative semigroups on the plane, II
International Journal of Mathematics and Mathematical Sciences, 1985 A positive semiroup is a topological semigroup containing a subsemigroup N isomorphic to the multiplicative semigroup of nonnegative real numbers, embedded as a closed subset of E2 in such a way that 1 is an identity and 0 is a zero.

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

On the orbits of G-closure points of ultimately nonexpansive mappings
Fixed Point Theory and Applications, 2006 Let X be a closed subset of a Banach space and G an ultimately nonexpansive commutative semigroup of continuous selfmappings. If the G-closure of X is nonempty, then the closure of the orbit of any G-closure point is a commutative topological group.

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

On absorption in semigroups and $n$-ary semigroups [PDF]
Logical Methods in Computer Science, 2015 The notion of absorption was developed a few years ago by Barto and Kozik and immediately found many applications, particularly in topics related to the constraint satisfaction problem.
