FUZZIFYING CLOSURE SYSTEMS AND CLOSURE OPERATORS
2011In this paper, we propose the concepts of fuzzifying closure systems and Birkhoff fuzzifying closure operators. In the framework of fuzzifying mathematics, we find that there still exists a one to one correspondence between fuzzifying closure systems and Birkhoff fuzzifying closure operators as in the case of classical mathematics.

On the Succinctness of Closure Operator Representations
2014It is widely known that closure operators on finite sets can be represented by sets of implications (also known as inclusion dependencies) as well as by formal contexts. In this paper, we consider these two representation types, as well as generalizations of them: extended implications and context families.

Insertion operations: Closure properties
Bull. EATCS, 1993The paper investigates closure properties of families of languages (in Chomsky hierarchy) under various variants of insertion operations as introduced by the author [On insertion and deletion operations in formal languages, PhD Thesis, Univ. of Turku, Dept. of Math., 1991].
