**Canonical Transformations in Quantum Mechanics**

by Arlen Anderson

**Publisher**: arXiv 1993**Number of pages**: 43

**Description**:

Quantum canonical transformations are defined algebraically outside of a Hilbert space context. This generalizes the quantum canonical transformations of Weyl and Dirac to include non-unitary transformations. The importance of non-unitary transformations for constructing solutions of the Schroedinger equation is discussed.
