Abstract:
The paper suggests and illustrates a simple unified approach to deriving upper bounds for the dominant eigenvalues of the so-called PF matrices (or matrices with the Perron–Frobenius property) from those for the Perron root of a nonnegative matrix.
Key words and phrases:spectral radius, nonnegative matrices, Perron root, Perron–Frobenius property, dominant eigenvalue, upper bounds.
