Deng, Julong Grey information space. (English) Zbl 0722.94003 J. Grey Syst. 1, No. 2, 103-117 (1989). Summary: This paper opens up the equivalence relation in algebra, using a topological concept, the grey information space (or the grey influence space) such that the grey factor space is developed. The metric space and the grey relational space refer to a special case. Some definitions, propositions and theorems concerning the aforesaid spaces are proposed.
