EL-hyperstructures: an overview

Michal Novak

Abstract


This paper gives a current overview of theoretical background of a special class of hyperstructures constructed from quasi / partially or dered (semi) groups using a construction known as the "Ends lemma". The paper is a collection of both older and new results presented at AHA 2011.


Keywords


group, hyperstructure, partial ordering, quasi order- ing, semigroup.
