摘要

In this paper, the author considers the nonlinear p-Laplacian Choquard equation on a weighted lattice graph. Under some suitable conditions on the potential function, the author proves that if the nonlinearity satisfies some growth conditions, the equation under study has a strictly positive solution. Compared with previous results, the conditions on the potential are relaxed and p can take any value in \((1,+\infty )\) ( 1 , + ) . Moreover, to our knowledge, there is currently no existence result for the p-Laplacian Choquard equation with the nonlinearity on lattice graphs.
