摘要

We study independently identically distributed random compositions of the Gauss and Rényi maps that are related to Diophantine approximation. Elaborating on methods in ergodic theory, thermodynamic formalism and large deviations, we prove that weighted cycles of this random dynamical system equidistribute with respect to the Gauss–Rényi measure. We obtain both annealed (sample-averaged) and quenched (samplewise) results.
