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…
On nonexistence and existence of positive global solutions to heat equation with a potential term on Riemannian manifolds
Qingsong Gu, Yuhua Sun, Fanheng Xu
We reinvestigate nonexistence and existence of global positive solutions to heat equation with a potential term on Riemannian manifolds. Especially, we give a very natural sharp co…
Metrics on the Sierpinski carpet by weight functions
Qingsong Gu, Hua Qiu, Huo-Jun Ruan
We construct certain metrics on the Sierpinski carpet via a class of self-similar weight functions. Using these metrics and by applying known results, we obtain the two-sided sub-G…
On a recursive construction of Dirichlet form on the Sierpiński gasket
Qingsong Gu, Ka-Sing Lau, Hua Qiu
Let denote the -th level Sierpiński graph of the Sierpiński gasket . We consider, for any given conductance on , the Dirchlet form …
