A Multistructure Created By Coverings Of A Set
Abstract
This paper focuses on a certain construction of a multistructure on the set of all coverings on the universal set U and discusses properties of this multistructure. The construction itself uses a concept dual to the Ends Lemma, called Beginnings Lemma, which is proved in the paper.
