摘要：

In this paper we shall provide sufficient conditions on the non-positive function f(i,u(1),...,u(n-1)) so that the boundary value problem (BVP) given by (E) Delta(n)u(i) + mu f(i, u(i), Delta u(i),..., Delta(n-2)(i)) = 0, and (BC) Delta(m)u(0) = 0, 0 less than or equal to m less than or equal to n- 3,alpha Delta(n-2)(0) -beta Delta(n-1)u(0) = 0, gamma Delta(n-2)u(T + 1) + delta Delta(n-1)u(T + 1) = 0, has at least one positive solution.
