Ordered Γ-semihypergroup of the Associated Γ-semihypergroup with All Relative Bi-Γ-hyperideals

Annals of Communications in Mathematics
n this paper, the main goal is to study an ordered Γ-semihypergroup H in the context of the characterizations of the associated Γ-semihypergroup B(H) of all bi-Γ-hyperideals of H. We show that an ordered Γ-semihypergroup H is a Clifford ordered Γ-semihypergroup if and only if B(H) is a semilattice.

Ordered Response Models [PDF]

We discuss regression models for ordered responses, such as ratings of bonds, schooling attainment, or measures of subjective well-being. Commonly used models in this context are the ordered logit and ordered probit regression models.

Ordered Response Models for Sovereign Debt Ratings [PDF]

Using ordered logit and probit plus random effects ordered probit approaches, we study the determinants of sovereign debt ratings. We found that the last procedure is the best for panel data as it takes into account the additional cross-section error ...

Hyperfilters and fuzzy hyperfilters of ordered semihypergroups

Journal of Intelligent and Fuzzy Systems, 2015
Abstract In this paper, we introduce the concept of hyperfilters of an ordered semihypergroup, and present some examples in this respect. Furthermore, we define and discuss the fuzzy hyperfilters of ordered semihypergroups.

Uni-soft hyperideals of ordered semihypergroups

Journal of Intelligent and Fuzzy Systems, 2018
The main goal of this paper is to study ordered semihypergroups in the framework of uni-soft left (right) hyperideals. The notions of uni-soft semihypergroups, uni-soft left (right) hyperideals are introduced, and the related properties are investigated.

Characterizations of (fuzzy) bi-hyperideals in ordered semihypergroups

Journal of Intelligent and Fuzzy Systems, 2015
Abstract In this paper, we study the concept of fuzzy bi-hyperideals in ordered semihypergroups and we present some examples in this respect. We give the main theorem which characterizes the bi-hyperideals in terms of fuzzy bi-hyperideals.

On fuzzy interior Γ-hyperideals in ordered Γ-semihypergroups

Journal of Intelligent and Fuzzy Systems, 2017
In this paper, we introduce the concept of interior Γ-hyperideals of ordered Γ-semihypergroups, which is a generalization of the concept of interior Γ-hyperideals of Γ-semihypergroups to ordered Γ-semihypergroup theory, and investigate its related properties.
