引入了基于模糊集的∈-软集和q-软集的概念,给出了一个∈-软集和q-软集为伪BL-代数的软(蕴涵)滤子的若干刻画。利用伪BL-代数的(∈,∈∨q)-模糊(蕴涵)滤予的概念,给出一个∈-软集为软(蕴涵)滤子的描述。
The notions of ∈ -soft set and q-soft set based on a fuzzy set are introduced, and characterizations for an ∈ - soft set and a q-soft set to be soft (implicative) filters of a pseudo-BL algebra are given. Using the notion of ( ∈ , ∈∨ q)-fuzzy (implicative) filters of pseudo-BL algebras, characterizations for an ∈ -soft set to be soft (implicative) filters are established.
