> /A celebrated example in algebraic geometry is the space of stable n-pointed algebraic curves of genusg, due to Deligne--Mumford and Knudsen. It has a delightful combinatorial structure based on weighted graphs./
> /Recent papers of Branetti, Melo, Viviani and of Caporaso defined an entirely different moduli space parametrizing tropical curves, a type of weighted metrized graphs generalizing earlier constructions of Culler and Vogtmann, Mikhalkin and others. It also has a delightful combinatorial structure based on weighted graphs./
> /One is led to ask whether there is a geometric connection between these moduli spaces; such questions were asked by Caporaso, Baker--Rabinoff--Payne, and Viviani./
> /In joint work with Caporaso and Payne, we show that indeed there is a connection, and a very nice one, which passes through a third type of geometry, nonarchimedean analytic geometry./
> /My goal is to give an intuitive description of the moduli spaces and the connection between them without requiring knowledge of algebraic geometry or analytic geometry/.
