摘要
引入带门槛的模糊B-子代数的概念,并讨论其性质.利用上水平集刻画了带门槛的模糊B-子代数,证明了在同态满射下,带门槛的模糊B-子代数的像和原像分别仍然是带门槛的模糊B-子代数.
The concept of the fuzzy B-sub-algebra with thresholds is introduced.Some of its properties are established.A characterization of the fuzzy B-subalgebra with thresholds is established by using upper level sets.It is proved that homomorphism images and homomorphism preimages of the fuzzy B-subalgebra with thresholds are also fuzzy B-subalgebras with the same thresholds under homomorphic epimorphism.
