Abstract

Matrices with entries that are smooth functions of a variable $\lambda \in L$ and non-negative when $\lambda \in L_{-}\subset L$ are considered. Perron-Frobenius theory applies when the entries are non-negative. Here, analogous results are shown to hold in neighbourhood of $L_{-} $, with the various quantities varying smoothly. The main examples are matrices with entries that are (i) Fourier-Stieltjes transforms of finite measures and (ii) Laplace-Stieltjes transforms, which arise from Markov-additive processes.
