The properties of an oscillating power sequence of an n x n fuzzy matr
ix have been studied. The necessary and sufficient conditions have bee
n established for a power sequence to be oscillatory. Furthermore, the
oscillation index was detailed to some degree; especially for some ty
pical Boolean matrices. It is also shown that the period index set of
the power sequences of fuzzy matrices of order n is not bounded from a
bove by a power of n for all integers n. (C) 1998 Elsevier Science B.V
