Multiplicity of Solutions of Weighted (p,q)-Laplacian with Small Sources and High-Order Perturbations，Huijuan Song，Jingxue Yin，In this paper we study the existence of infinitely many solutions to the degenerate quasilinear elliptic sy stem -div(h1(x)|▽u|p-2▽u)=d(x)|u|r-2u+Gu(x,u,v) inΩ, -div(h2(x)|
