Existence of multiple positive solutions for one-dimensional p-Laplacian

Abstract: In this paper we consider the multipoint boundary value problem for one-dimensional p-Laplacian φ p (u ) + f (t, u) = 0, t ∈ (0, 1), subject to the boundary value conditions:where φ p (s) = |s| p−2 s, p > 1, ξ i ∈ (0, 1) with 0 < ξ 1 < ξ 2 < · · · < ξ n−2 < 1, and a i , b i satisfy a i , b i ∈ [0, ∞], 0 < n−2 i=1 a i < 1, and n−2 i=1 b i < 1. Using a fixed point theorem for operators on a cone, we provide sufficient conditions for the existence of multiple (at least three) positive solutions to the above bound… Show more

“…We can see easily that all the results obtained in [1], [2], [4], [6], [7] are the existence of positive solutions. Seeing such a fact, we cannot but ask "how can we find the solutions since the solutions exist definitely?"…”

“…The purpose of this paper is to consider the existence of symmetric or monotone positive solutions and establish a corresponding iterative scheme for the nonlinear two-point singular boundary value problem (BVP) with a p-Laplacian operator (1) (ϕ p (u )) + q(t)f (u) = 0, 0 < t < 1,…”

“…For details, see for example, Refs [1,2,5], in the case p=2 see [6], and for case λ = 1, see [7,8,9]. In a recent paper [4], Hai considered the boundary value problem ∆u + λa(t)f (u) = 0, t ∈ Ω,…”
