This book treats some basic topics in the spectral theory of dynamical systems, where by a dynamical system we mean a measure space on which a group of automorp
This book discusses basic topics in the spectral theory of dynamical systems. It also includes two advanced theorems, one by H. Helson and W. Parry, and another
Canonical systems occupy a central position in the spectral theory of second order differential operators. They may be used to realize arbitrary spectral data,
