Let T > 5 be an integer, T = {1, 2, ... , T}. We are concerned with the global structure of positive solutions set of the discrete second-order boundary value problems Delta(2)u(t - 1) + rm(t)f(u(t)) = 0, t is an element of T, u(0) = u(T + 1) = 0, where r is an element of R is a parameter, m : T -> R changes its sign and m(t) not equal 0 for t is an element of T.
