Semihypergroup-Based Graph for Modeling International Spread of COVID-n in Social Systems

open access: yesMathematics, 2022
Graph theoretic techniques have been widely applied to model many types of links in social systems. Also, algebraic hypercompositional structure theory has demonstrated its systematic application in some problems. Influenced by these mathematical notions,

Inverse Semihypergroups

open access: yesWSEAS TRANSACTIONS ON MATHEMATICS, 2020
The concept of inverse semihypergroup is a generalization of the concept of inverse semigroup. In this paper we defined an orthodox semihypergroup S as it is a regular semihypergroup in which the set of idempotents of S forms a subsemihypergroup. We also presented a new definition of inverse semihypergroup S as each element x ∈ S has a unique inverse s

On hypercyclic fully zero-simple semihypergroups [PDF]

open access: yes, 2019
Let I be the class of fully zero-simple semihypergroups generated by a hyperproduct. In this paper we study some properties of residual semihypergroup (H_+; star) of a semihypergroup (H; \u25e6)in I. Moreover, we find sufficient conditions for (H; \u25e6)

(m, n)-Hyperfilters in Ordered Semihypergroups

open access: yesKragujevac Journal of Mathematics, 2022
we generalize concepts of left hyperfilters, right hyperfilters and hyperfilters of an ordered semihypergroup by introducing concepts of left-m-hyperfilters, right-n-hyperfilters and (m,n)-hyperfilters of an ordered semihypergroup. Then, some properties of these generalized hyperfilters have been studied. Finally, left-m-hyperfilters (resp. right-n-hyperfilters,

Semihypergroups obtained by merging of 0-semigroups with groups [PDF]

open access: yes, 2018
We consider the class of 0-semigroups (H;star) that are obtained by adding a zero element to a group (G; cdot) so that for all x,yin G it holds x star y not=0 Rightarrow x star y = xy. These semigroups are called 0-extensions of (G; cdot).

F-Hypergroups of Type U on the Right [PDF]

open access: yesMathematics Interdisciplinary Research, 2020
In this paper, first we introduce F-hypergroups of type U on the right. We will prove that every right scalar identity of an F-hypergroup of type U on the right of size ≤ 5 is also a left identity.

On Further Properties of Fully Zero-Simple Semihypergroups [PDF]

open access: yes, 2019
Let $mfF_0$ the class of fully zero-simple semihypergroups. In this paper we study the main properties of residual semihypergroup $(H_+, star)$ of a semihypergroup $(H, circ)$ in $mfF_0$.

Some Properties of Relative Bi-(Int-)Γ-Hyperideals in Ordered Γ-Semihypergroups

open access: yesFrontiers in Physics, 2020
In this article, we study the concept of relative bi-Γ-hyperideals (J-bi-Γ-hyperideals) in ordered Γ-semihypergroups and present some related examples of this concept.

On Certain Proximities and Preorderings on the Transposition Hypergroups of Linear First-Order Partial Differential Operators

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014
The contribution aims to create hypergroups of linear first-order partial differential operators with proximities, one of which creates a tolerance semigroup on the power set of the mentioned differential operators.
