Simple lift of non-simple closed curves

Geometric Topology 2024-06-07 v2

Abstract

Given a compact, oriented surface SS of finite genus and finitely many boundary components, we provide examples of finite covers S~\tilde{S} of SS and non-simple closed curves γ\gamma on SS which lifts to simple closed curves on S~\tilde{S}. In particular, given any positive integer n2n\geq 2, we construct explicit non-simple closed curves on SS which has a simple lift to a degree nn cover of SS.
