Finite graphs can be viewed, in many respects, as discrete analogues

of algebraic curves. In this talk, we consider this analogy in the

context of linear equivalence of divisors on a graph. We will state a

graph-theoretic version of the

proof. Additionally, we will discuss harmonic morphisms between graphs

and connections of our results to tropical geometry. This is joint

work with Matt Baker.

*Riemann-Roch theorem*, and outline itsproof. Additionally, we will discuss harmonic morphisms between graphs
