Description

Wigner's theorem is a fundamental part of the mathematical formulation of quantum mechanics.

The theorem characterizes unitary and anti-unitary operators as symmetries of quantum mechanical systems, and is a key result when relating preserver problems to quantum mechanics.

At the heart of this book is a geometric approach to Wigner-type theorems, unifying both classical and more recent results.

Readers are initiated in a wide range of topics from geometric transformations of Grassmannians to lattices of closed subspaces, before moving on to a discussion of applications.

An introduction to all the key aspects of the basic theory is included as are plenty of examples, making this book a useful resource for beginning graduate students and non-experts, as well as a helpful reference for specialist researchers.
