Algebraic Geometry in Outer Space |
Abstract |
Classical Riemann surface theory has an interesting analogue for metric graphs (connected graphs whose edges are assigned lengths) in which the complex numbers are replaced by the tropical numbers and rational functions are replaced by piecewise linear functions with integer slopes. I’ll explore some (hopefully interesting) metric graph versions of classical constructions for Riemann surfaces and talk a little about how outer space is and isn’t like the moduli space of Riemann surfaces from this point of view. |
