在双极值模糊软集理论的基础上,给出了双极值模糊(反)软子群的概念,讨论了它们的一些相关性质及等价刻画。提出了双极值模糊软映射下双极值模糊软集的像与原像的概念,并研究了双极值模糊软同态下双极值模糊(反)软子群的同态像与原像的初等性质。
The notions of bipolar-value fuzzy(anty-)soft subgroups based on the theory of bipolar-value fuzzy soft sets are given and several related properties and equivalent characterizations are discussed. Furthermore, the definitions of image and preimage of a bipolar-value fuzzy soft set are introduced and some preliminary properties of the image and preimage of a bipolar-value fuzzy(anty-)soft subgroup under a bipolar-value fuzzy soft homomorphism are investigated.
