This paper is devoted to the study of the following nonlocal p-Laplacian functional differential equation − φp(x (t)) = λ f(t,x(t),x (t)) 1 0 f(s,x(s),x (s))dsn , 0 < t < 1, subject to multi point boundary conditions. We obtain some results on the existence of at least one (when n ∈ Z+ ) or triple (when n = 0 ) pseudo-symmetric positive solutions by using fixedpoint theory in cone.
Keywords: boundary value problem, pseudo-symmetric solutions, p-Laplacian, LeggettWilliams fixed point theorem, Guo-Krasnoselskii fixed point theorem.
