The goal of this talk is to present notions of boundary and curvature on combinatorial graphs.  These will lead to some nice new theorems, at least some of which connected to game theory, as well as a whole bunch of fun open problems and some mysterious phenomena (certain linear systems of equations being solvable (why?), certain eigenvectors of matrices being nearly constant (why?), the existence of tiny subsets of vertices with magic properties (why??)).  I promise lots of pictures of graphs.

Note: This talk begins with a pre-seminar (aimed at graduate students) at 4:00–4:30. The main talk starts at 4:40.
