✦ Synopsis

Focusing on the behavior of the principal diagonal elements of A k, a new classification has been introduced, which is called circularly k-dominating. It turns out that the convergence index or the oscillating index of the power sequence of an n x n fuzzy matrix of the circularly k-dominating type is bounded by nk + n --k from above, and if it is oscillating, then the period index PA is a factor of k. The fuzzy matrices of the 2-dominating type were discussed in detail. It was shown that the 2-dominating type is a more general class than those have been discussed before, and the results established for matrices of 2-dominating type is as good as the results obtained for controllable matrices. Therefore most commonly used types of fuzzy matrices can be examined under the framework of 2-dominating matrices, and the convergence index or oscillating index can be estimated based on the results.

The properties of an oscillating power sequence of an n Γ— n fuzzy matrix have been studied. The necessary and sufficient conditions have been established for a power sequence to be oscillatory. Furthermore, the oscillation index was detailed to some degree; especially for some typical Boolean matric

By introducing a new classification, the essential role of the principal diagonal elements for the convergence of the power sequence of a fuzzy matrix A, is exported at the level of A itself. The established theorems cover those of monotone or nearly monotone increasing fuzzy matrices. The convergen

In the literature, the limiting behavior of powers of a fuzzy matrix has been studied with max-product composition. Pang and Guu proposed a simple and e ective characterization for the limiting behavior with the notion of asymptotic period. In this paper, we shall extend Pang and Guu's work to the r
