Principal Eigenvalues of a Second-Order Difference Operator with Sign-Changing Weight and Its Applications

Let T>2 be an integer and T={1,2,…,T}. We show the existence of the principal eigenvalues of linear periodic eigenvalue problem -Δ2u(j-1)+q(j)u(j)=λg(j)u(j),  j∈T, u(0)=u(T),  u(1)=u(T+1), and we determine the sign of the corresponding eigenfunctions, where λ is a parameter, q(j)≥0 and q(j)≢0 in...
