Heat kernel estimates on connected sums of parabolic manifolds

Alexander Grigor'yan, Satoshi Ishiwata, Laurent Saloff-Coste

We obtain matching two sided estimates of the heat kernel on a connected sum of parabolic manifolds, each of them satisfying the Li-Yau estimate. The key result is the on-diagonal…

Existence of positive solutions to some nonlinear equations on locally finite graphs

Alexander Grigor'yan, Yong Lin, Yunyan Yang

Let $G = (V, E)$ be a locally finite graph, whose measure $μ (x)$ have positive lower bound, and $Δ$ be the usual graph Laplacian. Applying the mountain-pass theorem due to Ambrosetti-…

Kazdan-Warner equation on graph

Alexander Grigor'yan, Yong Lin, Yunyan Yang

Let $G = (V, E)$ be a finite graph and $Δ$ be the usual graph Laplacian. Using the calculus of variations and a method of upper and lower solutions, we give various conditions such th…

Yamabe type equations on graphs

Alexander Grigor'yan, Yong Lin, Yunyan Yang

Let $G = (V, E)$ be a locally finite graph, $Ω \subset V$ be a bounded domain, $Δ$ be the usual graph Laplacian, and $λ_{1} (Ω)$ be the first eigenvalue of $- Δ$ with respect to Dirichlet…
