Abstract

This paper is concerned with the following third-order m-point boundary value problem $${ \left\{ \begin{array} \ u′′′(t)=f(t, u (t), u′(t), u′′(t))+ e (t), \ 0 < t < 1, \\ u(0) = \sum_{i=1}^{m−2} k_iu (ξ_i), u′ (0) = u′(1) = 0, \end{array} \right. }$$ where ${ f : (0, 1) × R^3 → R }$ is a function satisfying Carathéodory’s conditions, ${ e:(0, 1) → R \ and \ t(1 − t) e (t) ∈ L^1 [0, 1], 0 < ξ_1 < ξ_2 < · · · < ξ_{m−2} < 1, k_i ∈ R (i = 1, 2, . . . , m − 2) \ and }$ ${ \sum_{i=1}^{m−2} k_i \neq 1.}$ Some existence criteria of at least one solution are established by using the well-known Leray-Schauder Continuation Principle.
