On the Equal-height Elements of the Fuzzy Subgroups

The properties of the equal height elements of the fuzzy subroups and the classification of groups by its fuzzy subgroups are discussed.

Homomorphic Properties of Fuzzy Rough Groups

This paper is devoted to the discussion of homomorphic properties of fuzzy rough groups.The fuzzy approximation space was generated by fuzzy normal subgroups and the fuzzy rough approximation operators were discussed in the frame of fuzzy rough set model.The basic properties of fuzzy rough approximation operators were obtained.
