open access: yesJournal of New Theory, 2016
In this paper the notions of intuitionistic anti fuzzy bi-ideal, intuitionistic anti fuzzy interior ideal, intuitionistic anti fuzzy (1,2)-ideal in semigroups are introduced and some important characterizations have been obtained.

Tetrahedral chains and a curious semigroup

open access: yesExtracta Mathematicae, 2019
In 1957 Steinhaus asked for a proof that a chain of identical regular tetrahedra joined face to face cannot be closed. Świerczkowski gave a proof in 1959.

Generalized Polynomials on Semigroups

open access: yesAnnales Mathematicae Silesianae
This article has two main parts. In the first part we show that some of the basic theory of generalized polynomials on commutative semi-groups can be extended to all semigroups.
