The generalized roughness in LA-semigroups is introduced, and several properties of lower
and upper approximations are discussed. We provide examples to show that the lower …

In this paper, we study the idea of rough approximations in LA-polygroups, and present
some examples in this respect. In particular, we study some properties of rough LA …

In this paper we introduce and develop the concept of (∈, ∈ ∨ q_ k)(∈,∈∨ qk)-cubic
hyperideals,(∈, ∈ ∨ q_ k)(∈,∈∨ qk)-cubic bi-hyperideals,(∈, ∈ ∨ q_ k)(∈,∈∨ qk) …

In this paper we shall introduce the notion of rough prime ideals and rough fuzzy prime
ideals in LA-semigroups. We proved that the lower and the upper approximation of a prime …

An AG-groupoid S satisfying the identity x (yz)= z (xy) for all x, y, z∈ S is called a CA-AG-
groupoid. In this article the notions of equivalence relation and congruence is extended to …
