摘要:
For each n greater-than-or-equal-to 3, we characterize the linear operators, T, on the n x n fuzzy matrices that preserve commutativity strongly (that is, T(X) commutes with T(Y) if and only if X commutes with Y, for all X and Y). Characterizations of the corresponding linear operators on the fuzzy symmetric matrices are also obtained.
