Pointwise subexponential growth and near-diffusive displacement on bounded-degree graphs with non-negative Ollivier--Ricci curvature
Chiyu Zhou
The paper establishes subexponential upper bounds on the displacement of continuous-time random walks and on volume growth for locally finite graphs with bounded degree and non‑neg…

Quantitative Obata's theorem in discrete setting
Shiping Liu, Chiyu Zhou
Under mild assumptions, we show that a connected weighted graph with lower Ricci curvature bound in the sense of Bakry-Ãmery and the -th non-zero Laplacian eigenvalue…
