Schrödinger operators, typically formulated as −Δ + V where Δ denotes the Laplacian and V a potential function, are central to quantum mechanics and spectral theory. A key focus in recent ...
Journal of Operator Theory, Vol. 70, No. 1 (Summer 2013), pp. 109-144 (36 pages) We present a variant of Mourre's commutator theory. We apply it to prove the limiting absorption principle for ...
We consider the commutator of Calderón-Zygmund operator and multiplication operator by b, that is, the commutator of Coifman, Rochberg and Weiss. We study the boundedness of this operator on the Hardy ...
