In this paper, we introduce and study the concept of almost continuity in weak structures (Császár in Acta Math Hung 131(1--2):193--195, 2011) and discuss some of its characteristic properties. Finally, we give some applications of this new kind of continuity.

The aim of this paper is mainly to study the (L, M)-fuzzy measurability in view of degree.

Such kind of degrees is proved to satisfy some axioms of (L, M)-fuzzy σ-algebra. Additionally, we define and...
