摘要：
In this paper, we consider the following p-Laplacian multipoint boundary value problem on time scales: (phi(p) (u(Delta)(t)))(del) + a(t) f (t, u(t)) = 0, t is an element of [0, T](T), phi(P) (u(Delta)(0)) = (n-2)Sigma(i=1)a(i)phi(p)(u(Delta)(xi(i))), u(T) = (n-2)Sigma(i=1)b(i)u(xi(i)), where phi(p)(s) = vertical bar s vertical bar(p-2)s, p > 1, xi(i) is an element of [0, T](T), 0 < xi(1) < xi(2) < ... < xi(n-2) < rho(T). By using fixed point index, we provide some sufficient conditions for the existence of multiple positive solutions to the above boundary value problem. Especially, the nonlinear term f(t, u) is allowed to change sign. As an application, an example is given to demonstrate our result. (C) 2008 Elsevier Inc. All rights reserved.
