Irreducible Sign K-Potent Sign Pattern Matrices
Mathematics and Natural Sciences
The sign pattern matrix A is called sign k-potent if k is the smallest positive integer for which Ak+1=A. We characterize the irreducible pattern matrices that are sign k-potent and provide a canonical form for such matrices.
