Abstract: | This paper deals with the existence of multiple positive solutions for a class of nonlinear singular four-point boundary value
problem with p-Laplacian: where φ(x) = |x|
p−2
x, p > 1, a(t) may be singular at t = 0 and/or t = 1. By applying Leggett-Williams fixed point theorem and Schauder fixed point theorem, the sufficient conditions for the
existence of multiple (at least three) positive solutions to the above four-point boundary value problem are provided. An
example to illustrate the importance of the results obtained is also given.
