Abstract
In this paper, we introduce the concepts of (∈,∈∨(κ∗,qκ))-fuzzy left (right) ideals and (∈,∈∨(κ∗,qκ))-fuzzy ideals in ordered semirings. Some correspondence between (left, right) ideals and (∈,∈∨(κ∗,qκ))-fuzzy (left, right) ideals of ordered semirings are presented. Moreover, the notion of (κ∗,κ)-lower part of (∈,∈∨(κ∗,qκ))-fuzzy (left, right) ideals is defined and characterizations of different classes of ordered semirings are given.
