## TL;DR

The paper proposes a conjectural stratification of the Brill-Noether variety for general curves with fixed genus and gonality, supported by combinatorial and tropical evidence showing the expected number and dimension of components.

## Contribution

It introduces a conjectural stratification of Brill-Noether loci for fixed gonality curves and provides evidence using tropical and combinatorial methods.

## Key findings

- The Brill-Noether variety has at least as many irreducible components as predicted.
- Each component has the expected dimension.
- Analysis of tropical strata supports the conjecture.

## Abstract

We describe a conjectural stratification of the Brill-Noether variety for general curves of fixed genus and gonality. As evidence for this conjecture, we show that this Brill-Noether variety has at least as many irreducible components as predicted by the conjecture, and that each of these components has the expected dimension. Our proof uses combinatorial and tropical techniques. Specifically, we analyze containment relations between the various strata of tropical Brill-Noether loci identified by Pflueger in his classification of special divisors on chains of loops.
