C0-Groups, Commutator Methods and Spectral Theory of N-Body Hamiltonians by Werner O. Amrein, Anne Boutet de Monvel, Vladimir Georgescu.
The conjugate operator method is a powerful recently developed technique for studying spectral properties of self-adjoint operators. One of the purposes of this volume is to present a refinement of the original method due to Mourre leading to essentially optimal results in situations as varied as or...
