On the structure of the -algebra generated by the field operators and spectral analysis of the operators affiliated to it
Vladimir Georgescu, Andrei Iftimovici
We show that the -algebra generated by the field operators associated to a symplectic space is graded by the semilattice of all finite dimensional subspaces of . If …

Localizations at infinity and essential spectrum of quantum Hamiltonians: I. General theory
Vladimir Georgescu, Andrei Iftimovici
We isolate a large class of self-adjoint operators H whose essential spectrum is determined by their behavior at large x and we give a canonical representation of their essential s…
