The study of BCK-algebras was initiated by K. Iséki in 1966 as a generalization of the concept of set-theoretic difference and propositional calculus. The hyperstructure theory (called also multialgebras) is introduced in 1934 by Marty [6] at the 8th congress of Scandinavian Mathematicians. Around the 40’s, several authors worked on hypergroups, especially in France and in the United States, bu...

This study was performed to investigate the different methods of treating hyper granulation tissue on experimentally induced wounds in equine limbs. Wounds were induced by removal of a skin patch and subcutaneous tissue for about 5-7 cm width and 6-8 cm in length from the dorsal and lateral aspect of the fore and hind limbs below the carpal and tarsal joints. The wounds were left open without t...

We study infinitesimal deformations of autodual and hyper-holomorphic connections on complex vector bundles hyper-Kähler manifolds arbitrary dimension. In particular, we describe the DG Lie algebra controlling this deformation problem. Moreover, prove associative formality for derived endomorphisms a holomorphic bundle admitting projectively connection.

in this paper, the hyper - zagreb index of the cartesian product, composition and corona product of graphs are computed. these corrects some errors in g. h. shirdel et al.[11].

background: hyper ige syndrome (hies) is a rare primary immune deficiency, described as job`s syndrome characterized by increased serum levels of ige, eczema, recurrent cutaneous and pulmonary infections. in this paper, we presented a case of hyper ige syndrome.case presentation: a 16-year-old iranian boy presented with a one year history of skin lesions in knees and elbows was diagnosed of pso...

Using the notion of bipolar-valued fuzzy sets, the concepts of bipolar fuzzy (weak, s-weak, strong) hyper BCK-ideals are introduced, and their relations are discussed in [3]. Further properties are investigated in this article. We show that if Φ = (H ;μΦ , μ N Φ ) is a bipolar fuzzy (weak, strong) hyper BCK-ideal of a hyper BCK-algebra H, then the set I := {x ∈ H | μΦ(x) = μΦ(0), μΦ (x) = μΦ (0...
