double cones

By using the fixed point theorem in double cones,we study the existence of at least two positive solutions for the discrete three-point boundary value problem(BVP)Δ~2y(k-1)+a(k)f(k,y(k))=0,k∈N={1,2,…,T},Δy(0)=0,y(T+1)=βy(l),where f is allowed to change sign,l∈N_1=｛2,3,…,T-1｝,T∈｛3,4,…｝.
