Abstract

In this talk, we will discuss some necessary and sufficient conditions under which a closed curve on the bouquet of n-cirles can be lifted to a class of finite sheeted normal covering. We will also discuss some applications of these results to finite index normal subgroups of free groups. This is a joint work with Deblina Das.
