Flow Decomposition and Sharp Integral Fujita Criteria on Weighted Graphs

Qingsong Gu, Lu Hao, Xueping Huang +1

We study the Fujita phenomenon for semilinear heat inequalities generated by variable-speed Laplacians on infinite weighted graphs. Assuming that the graph carries a proper adapted…

A sharp integral criterion for the Lane--Emden system of inequalities on weighted graphs

Qingsong Gu, Lu Hao, Xueping Huang +1

We establish a sharp integral nonexistence criterion for the Lane--Emden system of inequalities \[ -Δu\ge v^p,\qquad -Δv\ge u^q, \qquad p,q>0,\quad pq>1, \] on arbitrary infinite,…

A Volume-Growth Criterion for the p-Laplace Inequality on Weighted Graphs

Qingsong Gu, Lu Hao, Xueping Huang +1

We prove a nonexistence result for nonnegative solutions of the quasi-linear elliptic inequality \[ -Δ_p u\ge σ(x)u^q \] on infinite locally finite connected weighted graphs, where…

Flow Decomposition, Green Testing, and Lane--Emden Inequalities on Weighted Graphs

Qingsong Gu, Lu Hao, Xueping Huang +1

We study positive solutions of the superlinear Lane--Emden inequality \[ -Δu\ge σu^q,\qquad q>1, \] on infinite locally finite weighted graphs and connected domains. When the Diric…

Sharp criteria for nonlocal elliptic inequalities on manifolds

Qingsong Gu, Xueping Huang, Yuhua Sun

Let be a complete non-compact Riemannian manifold and be a Radon measure on , we study the existence and non-existence of positive solutions to a nonlocal elliptic inequ…

Superlinear elliptic inequalities on weighted graphs

Qingsong Gu, Xueping Huang, Yuhua Sun

Let be an infinite, connected, locally finite weighted graph. We study the problem of existence or non-existence of positive solutions to a semi-linear elliptic inequality…
