Let LA = {fA, x : x is a partition of [0, 1]} be a class of piecewise linear maps associated with a transition matrix A. In this paper, we prove that if fA, x ∈ LA, then the Liapunov exponent λ (x) of fA, x is equal to a measure theoretic entropy hmA, x of fA, x, where mA, x is a Markov measure associated with A and x. The Liapunov exponent and the entropy are computable by solving an eigenvalue problem and can be explicitly calculated when the transition matrix A is symmetric. Moreover, we also show that maxx λ (x) = maxx hmA, x = log (λ1), where λ1 is the maximal eigenvalue of A.
