Discrete conjugacy criteria; discrete Riccati equation; phase function; generalized zero points

We establish conditions which guarantee that the second order difference equation \[\Delta ^2x_k+p_k x_{k+1}=0\] possesses a nontrivial solution with at least two generalized zero points in a given discrete interval
