Weighted estimates for the discrete Laplacian on the cubic lattice

Mathematical Physics 2017-05-04 v2 math.MP

Abstract

We consider the discrete Laplacian Δ\Delta on the cubic lattice Zd\mathbb Z^d, and deduce estimates on the group eitΔe^{it\Delta} and the resolvent (Δz)1(\Delta-z)^{-1}, weighted by q(Zd)\ell^q(\mathbb Z^d)-weights for suitable q2q\geq 2. We apply the obtained results to discrete Schr\"odinger operators in dimension d3d\geq 3 with potentials from p(Zd)\ell^p(\mathbb Z^d) with suitable p1p\geq 1.
