Abstract:

 By means of nonlinear Leray-Schauder alternative theorem and fixed point theorem in cones, the authors proved the existence of the solutions for one-dimensional singular p-Laplacian three-point boundary value problems under assumptive conditions. There is at least one positive value in the interval from zero to one.

Key words: LeraySchauder alternative theorem, fixed point theorem in cones, singular boundary value problem, existence of positive solution
