Abstract

The Aguilar-Balslev-Combes-Simon theory of resonances identifies the resonances of a self-adjoint operator H with the complex eigenvalues of a closed operator H(θ), which is obtained from H by the method of spectral deformation. In this chapter, we present the general theory of spectral deformation. This technique is applicable to many situations in mathematical physics, such as Schrödinger operator theory, quantum field theory, plasma stability theory, and the stability of solutions to certain nonlinear partial differential equations [Si4]. We will discuss the application to Schrödinger operators in Chapter 18.
