运用 Krasnoselskii 不动点定理, 本文考虑 p-Laplacian 混合边值问题 负的径向凸解的存在性, 其中B1 = {x ∈ ℝN: |x| p(s) = |s|p−2s, p > 1,f : [0,1] × [0,∞) → [0,∞) 连续. In this paper, by using Krasnoselskii fixed point throrem, we consider the existence of negative radial convex solutions for mixed boundary value problem of p-Laplacian where B1 = {x ∈ ℝN: |x| p(s) = |s|p−2s, p > 1,f : [0,1] × [0,∞) → [0,∞) is continuous.
