Eventually Pointed Principally Ordered Regular Semigroups [PDF]

open access: yes, 2020
An ordered regular semigroup, , is said to be principally ordered if for every  there exists . A principally ordered regular semigroup is pointed if for every element,  we have .

On dots in boxes, or Permutation pattern classes and regular languages [PDF]

open access: yes, 2015
This thesis investigates permutation pattern classes in a language theoretic context. Specifically we explored the regularity of sets of permutations under the rank encoding. We found that the subsets of plus- and minus-(in)decomposable permutations of

FUZZY INTERIOR HYPERIDEALS IN ORDERED SEMIHYPERGROUPS

open access: yes, 2016
We introduce the notions of an interior hyperideal and a fuzzy interior hyperideal of an ordered semihypergroup.  Then, we present a characterization of an interior hyperideal in terms of fuzzy interior hyperideals.

Ordered semihypergroup constructions

open access: yes, 2018
The concept of ordered semihypergroups is a generalization of the concept of ordered semigroups. In this paper, we study some aspects of hyperideals, bi-hyperideals and quasi-hyperideals of ordered semihypergroups.

Symmetry in Hyperstructure: Neutrosophic Extended Triplet Semihypergroups and Regular Hypergroups

open access: yes, 2019
The symmetry of hyperoperation is expressed by hypergroup, more extensive hyperalgebraic structures than hypergroups are studied in this paper. The new concepts of neutrosophic extended triplet semihypergroup (NET- semihypergroup) and neutrosophic ...

On Weakly Regular Fuzzy Ordered Ternary Semigroups [PDF]

open access: yes, 2016
Weakly regular ordered ternary semigroups are characterized in terms of fuzzy left, fuzzy right, fuzzy quasi-ideals and fuzzy bi-ideals, which generalizes and unifies results on weakly regular ordered semigroups and weakly regular ternary ...

General Equilibrium without Utility Functions: How far to go? [PDF]

open access: yes
How far can we go in weakening the assumptions of the general equilibrium model? Existence of equilibrium, structural stability and finiteness of equilibria of regular economies, genericity of regular economies and an index formula for the equilibria of ...

Ordered catenation and regular free disjunctive languages [PDF]

open access: yes, 1980
An operation, call it ordered catenation, on languages is introduced. Some well-known context-free and context-sensitive languages are able to express as ordered catenation of regular languages.
