Beyond Regular Semigroups [PDF]

open access: yes, 2012
The topic of this thesis is the class of weakly U-abundant semigroups. This class is very wide, containing inverse, orthodox, regular, ample, adequate, quasi-adequate, concordant, abundant, restriction, Ehresmann and weakly abundant semigroups.

Smarandache Idempotents infinite ring Zn and in Group Ring ZnG [PDF]

open access: yes, 2005
This paper has 4 sections. In section 1, we just give the basic definition of S-idempotents in rings. In section 2, we prove the existence of S-idempotents in the ring Zn where n = 2mp;m 2 N and p is an odd ...

Every group is a maximal subgroup of the free idempotent generated semigroup over a band [PDF]

open access: yes, 2013
Given an arbitrary group G we construct a semigroup of idempotents (band) BG with the property that the free idempotent generated semigroup over BG has a maximal subgroup isomorphic to G. If G is finitely presented then BG is finite. This answers several

Cyclic codes and primitive idempotents in the finite cyclic group algebras [PDF]

open access: yesEuropean Journal of Mathematics and Applications, 2022
We parallelly discuss the construction of cyclic linear codes as ideals in the finite cyclic group ring as well as zero-divisors therein. We also determine a complete set of primitive idempotents in the finite cyclic group ring over a field of ...

Maximal subgroups of free idempotent-generated semigroups over the full transformation monoid [PDF]

open access: yes, 2011
Let Tn be the full transformation semigroup of all mappings from the set {1, . . . , n} to itself under composition. Let E = E(Tn) denote the set of idempotents of Tn and let e ∈ E be an arbitrary idempotent satisfying |im (e)| = r ≤ n − 2. We prove that

Idempotents, free products and quandle coverings [PDF]

open access: yes, 2022
In this paper, we investigate idempotents in quandle rings and relate them with quandle coverings. We prove that integral quandle rings of quandles of finite type that are non-trivial coverings over nice base quandles admit infinitely many non-trivial ...

Semigroups of order-decreasing transformations [PDF]

open access: yes, 2012
Let X be a totally ordered set and consider the semigroups of orderdecreasing (increasing) full (partial, partial one-to-one) transformations of X. In this Thesis the study of order-increasing full (partial, partial one-to-one) transformations has been

Skew Pairs of Idempotents in Partial Transformation Semigroups

open access: yesMathematics, 2021
Let S be a regular semigroup. A pair (e,f) of idempotents of S is said to be a skew pair of idempotents if fe is idempotent, but ef is not. T. S. Blyth and M. H. Almeida (T. S. Blyth and M. H.
