Abstract

In this paper, we consider the dynamics of a skew-product map defined on the Cartesian product of the symbolic one-sided shift space on NN symbols and the complex sphere where we allow NN rational maps, R1,R2,,RNR_{1}, R_{2}, \cdots, R_{N}, each with degree di; 1iNd_{i};\ 1 \le i \le N and with at least one RiR_{i} in the collection whose degree is at least 22. We obtain results regarding the distribution of pre-images of points and the periodic points in a subset of the product space (where the skew-product map does not behave normally). We further explore the ergodicity of the Sumi-Urbanskii (equilibrium) measure associated to some real-valued H\"{o}lder continuous function defined on the Julia set of the skew-product map and obtain estimates on the mean deviation of the behaviour of typical orbits, violating such ergodic necessities.
