Gradient estimates on graphs with the $C D ψ (n, - K)$ condition

Yi Li, Qianwei Zhang

This paper investigates gradient estimates on graphs satisfying the $C D ψ (n, - K)$ condition with positive constants $n, K$ , and concave $C^{1}$ functions $ψ:(0,+\infty)\rightarrow\mat…

Existence of Solutions to a Class of Kazdan-Warner Equations on Finite Graphs

Yi Li, Qianwei Zhang

Let $G = (V, E)$ be a connected finite graph, $h$ be a positive function on $V$ and $λ_{1} (V)$ be the first non-zero eigenvalue of $- Δ$ . For any given finite measure $μ$ on $V$ , defi…
