Ultra LI-ideals in lattice implication algebras and MTL-algebras
Xiaohong Zhang, Keyun Qin, Wieslaw A. Dudek
A mistake concerning the ultra \textit{LI}-ideal of a lattice implication algebra is pointed out, and some new sufficient and necessary conditions for an \textit{LI}-ideal to be an…
Fuzzy n-ary groups as a generalization of Rosenfeld's fuzzy groups
Bijan Davvaz, Wieslaw A. Dudek
The notion of an -ary group is a natural generalization of the notion of a group and has many applications in different branches. In this paper, the notion of (normal) fuzzy …
Special types of intuitionistic fuzzy left h-ideals of hemirings
Wieslaw A. Dudek
Characteristic, normal and completely normal intuitionistic fuzzy left -ideals of hemirings are described.
Remarks to Glazek's results on n-ary groups
Wieslaw A. Dudek
It is a survey of the results obtained by K. Glazek's and his co-workers. We restrict our attention to the problems of axiomatizations of n-ary groups, classes of n-ary groups, pro…
Stationary subsets of functional Menger -algebras of multiplace functions
Wieslaw A. Dudek, Valentin S. Trokhimenko
A functional Menger -algebra is a set of n-place functions containing n projections and closed under the so-called Menger's compositions of n-place functions and the set-theo…
Stabilizers of functional Menger systems
Wieslaw A. Dudek, Valentin S. Trokhimenko
A functional Menger system is a set of -place functions containing projections and closed under the so-called Menger's composition of -place functions. We give the abstra…
