Fully indecomposable exponents of primitive matrices
Richard A. Brualdi, Bo Lian Liu · Proceedings of the American Mathematical Society · 1991
If A A is a primitive matrix, then there is a smallest power of A A (its fully indecomposable exponent) that is fully indecomposable, and a smallest power of A A (its strict fully indecomposable exponent) starting from which all powers are fully indecomposable. We obtain bounds on these two exponents.
