Equivalent Properties of CD Inequality on Graph

Understand

We study some equivalent properties of the curvature-dimension conditions $CD(n,K)$ inequality on infinite, but locally finite graph.

• These equivalences are gradient estimate, Poincar\'e type inequalities and reverse Poincar\'e inequalities.
• And we also obtain one equivalent property of gradient estimate for a new notion of curvature-dimension conditions $CDE'(\infty, K)$ at the same assumption of graphs.
