摘要
Let T be a time scale such that 0, T is an element of T. We consider the three-point boundary value problem for p-Laplacian dynamic equations on time scales T of the form (phi(p)(u(Delta)(t)))(del) + h(t)f (t, u(t)) = 0 for t is an element of (0, T)(T) with boundary conditions u(0) = 0, u(eta) = u(T), where T is symmetric in [eta, T](T) and phi(p)(u) = vertical bar u vertical bar(p-2) u with p > 1. By using a pseudo-symmetric technique and the five-functionals fixed-point theorem, we prove that the boundary value problem has at least three positive pseudo-symmetric solutions under some assumptions. As an application, an example is given to illustrate the result. (C) 2007 Elsevier Ltd. All rights reserved.
