Existence of three solutions for a poly-Laplacian system on graphs

Analysis of PDEs 2023-09-19 v1

Abstract

We deal with the existence of three distinct solutions for a poly-Laplacian system with a parameter on finite graphs and a (p,q)(p,q)-Laplacian system with a parameter on locally finite graphs.The main tool is an abstract critical points theorem in [Bonanno and Bisci, J.Math.Appl.Anal, 2011, 382(1): 1-8]. A key point in this paper is that we overcome the difficulty to prove that the G\mboxa^\hat{\mbox{a}}teaux derivative of the variational functional for poly-Laplacian operator admits a continuous inverse, which is caused by the special definition of the poly-Laplacian operator on graph and mutual coupling of two variables in system.
