<正>p-Laplacian Equations on Locally Finite Graphs Xiao Li HAN Meng Qiu SHAO Abstract This paper is mainly concerned with the following nonlinear p-Laplacian equation-Δ_pu(x)+(λa(x)+1)|u|~(p-2)(x)u(x)=f(x,u(x)),in V on a locally finite graph G=(V,E) with more general nonlinear term,whereΔ_p is the discrete p-Laplacian on graphs,p≥2.Under some suitable conditions on f and a(x),we can prove that the equation admits a positive solution by the Mountain Pass theorem and a ground state solution u_λvia the method of Nehari manifold,for anyλ> 1.In addition,asλ→+∞,we prove that the solution u_λconverge to a solution of the following Dirichlet problem 相似文献

Existence of solutions for fractional differential equation with p-Laplacian through variational method 下载免费PDF全文
In this paper, a class of fractional differential equation with p-Laplacian operator is studied based on the variational approach. Combining the mountain pass theorem with iterative technique, the existence of at least one nontrivial solution for our equation is obtained. Additionally, we demonstrate the application of our main result through an example. 相似文献

In this paper we consider a non-self-adjoint evolution equation on a compact Riemannian manifold with boundary. We prove a Harnack inequality for a positive solution satisfying the Neumann boundary condition. In particular, the boundary of the manifold may be nonconvex and this gives a generalization to a theorem of Yau.

In this paper we study a nonlinear elliptic differential equation driven by the p-Laplacian with a multivalued boundary condition of the Neumann type.
