Dispersive Decay Estimates for periodic Jacobi operators on the half-line

Amir Sagiv, Remy Kassem, Michael I Weinstein

We establish dispersive time-decay estimates for periodic Jacobi operators on the discrete half-line, $\mathbb{N}$. Specifically, we prove $t^{-1/2}$ decay in the weighted $\ell^\infty_{-1…
