Generalized Weisner designs and quasigroups.
Intuitionistic fuzzy -ideals.
On -permutable n-groups.
Rough subalgebras of some binary algebras connected with logics.
On fuzzy ideals in Hilbert algebras.
On ()-fuzzy filters of pseudo-BL algebras.
Remarks to Głazek's results on n-ary groups
This is a survey of the results obtained by K. Głazek and his co-workers. We restrict our attention to the problems of axiomatizations of n-ary groups, classes of n-ary groups, properties of skew elements and homomorphisms induced by skew elements, constructions of covering groups, classifications and representations of n-ary groups. Some new results are added too.
On the transfer principle in fuzzy theory.
We show in this paper that almost all results proved in many papers about fuzzy algebras can be proved uniformly and immediately by using so-called Transfer Principle.
On fuzzy topological subalgebras of BCC-algebras
We describe properties of subalgebras and BCC-ideals in BCC-algebras with a topology induced by a family of fuzzy sets.
