Positive Lyapunov exponent for random perturbations of predominantly expanding multimodal circle maps

A Blumenthal, Y Yang - arXiv preprint arXiv:1805.09219, 2018 - arxiv.org
We study the effects of IID random perturbations of amplitude $\epsilon> 0$ on the
asymptotic dynamics of one-parameter families $\{f_a: S^ 1\to S^ 1, a\in [0, 1]\} $ of smooth …
