摘要 利用混合单调算子,给出了奇异四阶差分方程边值问题{Δ~2[φ_p(Δ~2y(i-1))]+λF(i,y(i))=0,i∈[1,T+3],λ〉0;y(0)=y(T+4)=0;Δ2y(0)=Δ2y(T+2)=0正解的存在唯一性,其中φp(s)=|s|p-2s,p〉1,F∈C((0,T+4)×(0,+∞),(0,+∞)),[1,T+3]={1,2,…,T+3},[0,T+4]={0,1,2,…,T+4},并且非线性项F在y=0可能是奇异的. By means of a fixed point theorem,existence and uniqueness of positive solutions for four-order four-point nonlinear singular discrete boundary value problems with p-Lapacian operator.The theorems obtained are very general and complement previous known results.
