Title: Volume Doubling in graphs with nonnegative curvature
Emmanuel Russ - Aix-Marseille Université
Let G be a discrete infinite graph with bounded geometry, endowed
with a standard Laplacian. Assuming that the curvature of G (in the
sense of Bakry–Émery) is nonnegative, we show that the volume of balls
satisfies the doubling property, as in the case of Riemannian manifolds.
This is a joint work with Hervé Pajot.
