This work gives a computable formula for the average measure theoretic entropy of a family of expanding on average random Blaschke products, generalizing work by Pujals, Roberts and Shub Expanding maps of the circle revisited: positive Lyapunov exponents in a rich family. Ergodic Theory Dynam. Systems. 26 (6) (2006), 1931-1937 to the random setting. In doing so, we describe the random invariant measure and associated measure theoretic entropy for a class of admissible random Blaschke products, allowing for maps which are not necessarily expanding and may even have an attracting fixed point.
González‐Tokman et al. (Thu,) studied this question.
