₷Ꝗ-Neutrosophic Structures in Semigroup Theory [PDF]
Neutrosophic Sets and SystemsIn 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.

Neutrosophic Left Almost Semigroup [PDF]
Neutrosophic 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.

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

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

Semigroup compactifications by generalized distal functions and a fixed point theorem
International 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 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.

Semigroup theory applied to options
Journal of Applied Mathematics, 2002 Black and Scholes (1973) proved that under certain assumptions about the market place, the value of a European option, as a function of the current value of the underlying asset and time, verifies a Cauchy problem.

Koopman Operator Framework for Spectral Analysis and Identification of Infinite-Dimensional Systems
Mathematics, 2021 We consider the Koopman operator theory in the context of nonlinear infinite-dimensional systems, where the operator is defined over a space of bounded continuous functionals. The properties of the Koopman semigroup are described and a finite-dimensional

Soft Neutrosophic Bi-LA-semigroup and Soft Neutrosophic N-LA-seigroup [PDF]
Neutrosophic Sets and Systems, 2014 Soft set theory is a general mathematical tool for dealing with uncertain, fuzzy, not clearly defined objects. In this paper we introduced soft neutrosophic biLA-semigroup,soft neutosophic sub bi-LA-semigroup, soft neutrosophic N -LA-semigroup with the ...
