On derivations of EQ-algebras
Jie Liang, Xiao Long Xin, Jun Tao Wang · Journal of Intelligent & Fuzzy Systems · 2018
The main goal of this paper is to introduce the notions of derivations on EQ -algebras and obtain several special types of them. In this paper, we discuss some properties of useful derivations and give some characterisations of them. Then, we also show that the fixed point set of useful derivations is a good EQ -algebra. Moreover, we study simple ⊙-derivations and their adjoint derivations and prove that the fixed point set of simple ⊙-derivations and that of their adjoint derivations are order isomorphism. Furthermore, the quotient algebras induced by d -filter are studied.
