摘要
This paper concerns the compact group extension f: T-2 -> T-2, f(x, s)=(E(x), s + tau(x) mod 1) of an expanding map E : S-1 -> S-1. The dynamics of f and its stochastic perturbations have previously been studied under the so-called partial captivity condition. Here we prove a supplementary result that shows that partial captivity is a C-r generic condition on tau, once we fix E.
