THE UNIQUE SQUARE ROOT CONDITION FOR QUASI-ORDER HYPERGROUPS AND CONSTRUCTION OF A SUBQUASI-ORDER HYPERGROUP

Jan Chvalina in the paper: Commutative hypergroups in the sence of Marty and ordered sets has introduced a special type of hypergroups, so called quasi-order hypergroups and order hypergroups. By quasi-order hy...

UPPER ORDER HYPERGROUPS AS A REFLECTIVE SUBCATEGORY OF SUBQUASI-ORDER HYPERGROUPS

In the contribution the category of subquasi-order hypergroups SQOHG and their morphisms is introduced. This concept is the generalization of quasi-order hypergroups for quasi-order hypergroups and the corresponding reflect...

An example of subquasi-order hypergroup

The aim of this contribution is to give an example of subquasi-order hypergroup. By quasi-order hypergroups (order hypergroups) we mean the hypergroups determined by a binary relation of quasiordering (ordering). T...

Fuzzy Multi-Hypergroups

the innovative notion of fuzzy multisets and hypergroups. In particular, we use fuzzy multisets to introduce the concept of fuzzy multi-hypergroups as a generalization of fuzzy hypergroups. Different operations on fuzzy mu...

Quasi-order hypergroups and T-hypergroups

Quasi-order hypergroups were introduced by J. Chvalina in 90s of the last century. They form a subclass of the class of all hypergroups, i.e. structures a theorem whichallows an easy description of all quasi-order hypergroups

Abelizations of quasi-hypergroups as a reflexion.

Contribution is devoted to certain simple construction of commutative quasi-hypergroup from a quasi-hypergroup non-commtative, therefore to the abelization of quasi-hypergroups which are created the categorial reflection. T...

Closed, Reflexive, Invertible, and Normal Subhypergroups of Special Hypergroups

J. Jantosciak introduced several special types of subhypergroups (invertible, closed, normal, reflexive) of a general hypergroup and studied their relationship. In this article, the full description of such subhypergroups in hypergroups<...
