For any two points P=(p(1),p(2),,p(n)) and Q=(q(1),q(2),,q(n)) of n, we define the crisp vector PQ=(q(1)p(1),q(2)p(2),,q(n)p(n))=Q()P. Then we obtain an n-dimensional vector space En={PQ|for allP,Qn}. Further, we extend the crisp vector into the fuzzy vector on fuzzy sets of n. Let D˜,E˜ be any two fuzzy sets on n and define the fuzzy vector E˜D˜=D˜E˜, then we have a pseudo-fuzzy vector space.
