摘要
We are concerned with the nonlinear discrete periodic boundary value problem -Delta[p(t - 1)Delta u(t - 1)] + q(t)u(t) = rg(t)f(u(t)), t is an element of [1, T](z), (P) u(0) = u(T), p(0)Delta u(0) = p(T)Delta u(T), where r is a positive parameter. Optimal interval will be given to the parameter r to ensure that (P) has at least one positive solution. (C) 2009 Elsevier Ltd. All rights reserved.
