Existence of positive solutions for a class of discrete problems with(p,q)-Laplace operators
摘要
Abstract
By using the upper and lower solution method,this study proves the existence of positive solutions for a class of discrete problems with(p,q)-Laplace operators{-Δ(ϕp(Δu(t-1)))-Δ(ϕq(Δu(t-1)))=λf(u(t)),t∈[1,T]Z,Δu(0)=u(T+1)=0,where p>q>1,λ>0 is a parameter,T>2 is a fixed positive integer,[1,T]Z={1,2,…,T},ϕr(s)=|s|r-2 s,Δu(t)=u(t+1)-u(t),f:(0,∞)→R is p-sublinear at ∞ with possible singularity at 0.关键词
