摘要 研究下列具有p-Laplacian算子的四阶三点边值问题{(φp(u″(t)))″=f(t,u(t),u″(t)),t∈[0,1] u(0)-ξu(1)=0,u′(1)-ηu′(0)=0 u″(0)-a1u″(δ)=0,(φp(u″))′(1)-b1(φp(u″))′(δ)=0其中φp(s)=|s|p-2s,p>1,0<ξ,η<1,0<a1,b1<1,0<δ<1,f∈C([0,1]×R2,R).通过单调迭代方法获得迭代解. The fourth-order three-point boundary value problems with p-Laplaeian {(φp(u″(t)))″=f(t,u(t),u″(t)),t∈[0,1] u(0)-ξu(1)=0,u′(1)-ηu′(0)=0 u″(0)-a1u″(δ)=0,(φp(u″))′(1)-b1(φp(u″))′(δ)=0 is studied,where φp(s)=|s|p-2s,p〉1,0〈ξ,η〈1,0〈a1,b1〈1,0〈δ,1,f∈C([0,1]×R^2,R).The existence of iterative solutions is obtained by monotone iterative technique.
