Tropical trigonal curves
Margarida Melo, Angelina Zheng
We prove that the existence of a divisor of degree and Baker-Norine rank at least on a -edge connected tropical curve is equivalent to the existence of a non-degenerate…

Clifford representatives via the uniform algebraic rank
Myrla Barbosa, Karl Christ, Margarida Melo
In this paper, we introduce the uniform algebraic rank of a divisor class on a finite graph. We show that it lies between Caporaso's algebraic rank and the combinatorial rank of Ba…
