Abstract

In this chapter we discuss the construction of self-adjoint operators indicating the direction of time within the framework of standard quantum mechanics (Strauss 2011). Such operators will be referred to as Lyapunov operators. The particular construction of Lyapunov operators in this section will enable us to develop a formalism providing a good approximation to the Lax–Phillips theory for scattering problems involving Hamiltonians with semibounded spectra, as we do in Chap.  4. The construction of Lyapunov operators, moreover, has an intrinsic interest of its own.
