Abstract

Consider a non-autonomous continuous-time linear system in which the time-dependent matrix determining the dynamics is piecewise constant and takes finitely many values A1,,ANA_1, \dotsc, A_N. This paper studies the equality cases between the maximal Lyapunov exponent associated with the set of matrices {A1,,AN}\{A_1, \dotsc, A_N\}, on the one hand, and the corresponding ones for piecewise deterministic Markov processes with modes A1,,ANA_1, \dotsc, A_N, on the other hand. A fundamental step in this study consists in establishing a result of independent interest, namely, that any sequence of Markov processes associated with the matrices A1,,ANA_1,\dotsc, A_N converges, up to extracting a subsequence, to a Markov process associated with a suitable convex combination of those matrices.
