Neutrosophic LA-Semigroup Rings [PDF]
Neutrosophic Sets and Systems, 2015 Neutrosophic LA-semigroup is a midway structure between a neutrosophic groupoid and a commutative neutrosophic semigroup. Rings are the old concept in algebraic structures.

Journal of Mahani Mathematical Research, 2022 We know that $\Gamma-$ring, $\Gamma-$incline, $\Gamma-$semiring, $\Gamma-$semigroup are generalizations ofring, incline, semiring and semigroup respectively.

Simple semigroup graded rings [PDF]
Journal of Algebra and Its Applications, 2015 We show that if R is a, not necessarily unital, ring graded by a semigroup G equipped with an idempotent e such that G is cancellative at e, the nonzero elements of eGe form a hypercentral group and Re has a nonzero idempotent f, then R is simple if and only if it is graded simple and the center of the corner subring f ReGe f is a field.

On semisimple semigroup rings [PDF]
Proceedings of the American Mathematical Society, 1980 Let π \pi be a property of rings that satisfies the conditions that (i) homomorphic images of π \pi -rings are π \pi -rings and (ii) ideals of π \pi -rings are π \pi -rings.

Right derivations on ordered semigroups [PDF]
Journal of Hyperstructures, 2019 Over the last few decades, several authors have investigated the relationship between the commutativity of ring R and the existence of certain specified derivations of R.

Shellability of semigroup rings [PDF]
Nagoya Mathematical Journal, 2002 AbstractThe concepts of Λ-shellability of locally finite posets as well as of extendable sequentially Koszul algebras will be introduced. It will be proved that the divisor poset of a homogeneous semigroup ring is Λ-shellable if and only if the semigroup ring is extendable sequentially Koszul.

On (m, k) -type elements in the ring of integers modulo n [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2022 An element a in a ring R is said to be of (m, k)-type if a m = a k where m and k are positive integers with m > k ≥ 1. Let Xn(m, k) be the set of all (m, k)-type elements, X * n(m, k) be the set of all nonzero (m, k)-type elements, and Sn(m, k) be ...

International Journal of Mathematics and Mathematical Sciences, 2002 Let R be a ring. The circle operation is the operation a∘b=a+b−ab, for all a,b∈R. This operation gives rise to a semigroup called the adjoint semigroup or circle semigroup of R. We investigate rings in which the adjoint semigroup is regular. Examples are

The clique number of the intersection graph of a cyclic group of order with at most three prime factors [PDF]
ریاضی و جامعه, 2023 Let $G$ be a finite non-trivial group. The intersection graph $\Gamma(G)$, is a graph whose vertices are all proper non-trivial subgroups of $G$, and there is an edge between two distinct vertices $H $ and $K$ if and only if $H\cap K\neq 1$.
