An extension of the Perron-Frobenius theorem
Abstract
Starting from a rather simple theorem by Scheffold a set of sufficient conditions
is found for the system pAp = Bp to have a solution with p > 1 and p > 0, where A and B are
nxn positive matrices. It is shown that such a system would be an extension of the system
pAp = Ip for which the Perron-Frobenius theorem holds.
