TITLE: A Divisors on graphs
http://mathsci.kaist.ac.kr/~sangil/seminar/entry/20090107/
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 Riemann-Roch theorem, and outline its
proof. Additionally, we will discuss harmonic morphisms between graphs
and connections of our results to tropical geometry. This is joint
work with Matt Baker.
