Lifting divisors with imposed ramifications on a generic chain of loops

Abstract

Proves that if a curve has totally split reduction and the corresponding skeleton (as a metric graph) is a chain of loops with generic edge lengths, then every divisor on the graph with imposed ramification at the rightmost vertex $p$ of the skeleton lifts to a divisor class on the curve with the same ramification at some point $P$ that retracts to $p$, extending the work of Cartwright-Jensen-Payne. Gives a positive answer to lifting proper tropical intersections within a polytopal domain in an analytic torus.
