₷Ꝗ-Neutrosophic Structures in Semigroup Theory [PDF]

open access: yesNeutrosophic Sets and Systems
In this paper, we define and study a new fuzzy algebraic structure called ₷Ꝗ-neutrosophic fuzzy semigroups (₷Ꝗ-NFS) as a generalization of fuzzy algebra in the framework of ₷-semigroups.

On the structure theory of partial automaton semigroups [PDF]

open access: yesSemigroup Forum, 2020
We study automaton structures, i.e. groups, monoids and semigroups generated by an automaton, which, in this context, means a deterministic finite-state letter-to-letter transducer. Instead of considering only complete automata, we specifically investigate semigroups generated by partial automata.

Generating the full transformation semigroup using order preserving mappings [PDF]

open access: yes, 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 =

Representation of right zero semigroups and their semilattices by a transformation semigroup

open access: yesИзвестия высших учебных заведений. Поволжский регион: Физико-математические науки, 2022
Background. As is known, an arbitrary semigroup can be represented by a semigroup of transformations that are right shifts either in this semigroup itself or in the extended semigroup obtained from the original one by adding an outer unit. The problems

On maximal subgroups of free idempotent generated semigroups [PDF]

open access: yes, 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.

Neutrosophic Left Almost Semigroup [PDF]

open access: yesNeutrosophic Sets and Systems, 2014
In this paper we extend the theory of neutrosophy to study left almost semigroup shortly LAsemigroup. We generalize the concepts of LA-semigroup to form that for neutrosophic LA-semigroup.

Semigroup compactifications by generalized distal functions and a fixed point theorem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1991
The notion of “Semigroup compactification” which is in a sense, a generalization of the classical Bohr (almost periodic) compactification of the usual additive reals R, has been studied by J. F. Berglund et. al. [2].

A new characterization of a proper type B semigroup

open access: yesOpen Mathematics, 2020
In this paper, we develop the elementary theory of inverse semigroups to the cases of type B semigroups. The main aim of this paper is to study proper type B semigroups. We introduce first the concept of a left admissible triple.
