该文利用锥上的不动点定理,给出四阶超线性奇异p-Laplacian边值问题正解存在的充分必要条件.所给出的条件与非线性项的可积性有关.
Necessary and sufficient conditions for existence of positive solutions of fourth order singular superlinear p-Laplacian BVPs are established by employing the fixed point theorem in cones. The conditions involve the integral of the nonlinear terms.
