✦ Synopsis

we shall provide conditions on nonpositive function f(i, ~1,. . , u,_1) ~0 that t,he discrete boundary value problem

YA +'n(T + 1) + 6An-%(T + 1) = 0, has at least one positive solution. Then, we shall apply this result to establish several existence theorems which guarantee the multiple positive solutions.
