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 ...

Factorization formulae are given for commutators between any coupled operators, such as [( A × B ) j , ( C × D ) j ′ ], where J can be the angular momentum or other quantum numbers depending on the ...

A formula useful for evaluating the commutator anomaly for the Gauss law constraint operator is presented. This formula makes the perturbative calculation of the anomaly much simpler than previous ...
