Fermi Golden Rule, Feshbach Method and embedded point spectrum
Séminaire Équations aux dérivées partielles (Polytechnique) (1998-1999), Talk no. 23, 11 p.

A method to study the embedded point spectrum of self-adjoint operators is described. The method combines the Mourre theory and the Limiting Absorption Principle with the Feshbach Projection Method. A more complete description of this method is contained in a joint paper with V. Jak$\stackrel{ˇ}{\mathrm{s}}$ić, where it is applied to a study of embedded point spectrum of Pauli-Fierz Hamiltonians.
