Riemann-Roch inequality for smooth tropical toric surfaces
Ken Sumi
For a divisor on a tropical variety , we define two amounts in order to estimate the value of , which are described by terms of global sections and computed more…

Tropical Theta Functions and Riemann-Roch Inequality for Tropical Abelian Surfaces
Ken Sumi
We show that the space of theta functions on tropical tori is identified with a convex polyhedron. We also show a Riemann-Roch inequality for tropical abelian surfaces by calculati…
