Mathematical foundations of quantum mechanics

This book, originally published in German in 1932 and translated into English in 1955, is a seminal work in the development of quantum theory.

John von Neumann presents a rigorous mathematical treatment of quantum mechanics, focusing on the theory of Hermitean operators and Hilbert spaces.

He addresses key issues such as quantum statistical mechanics, measurement processes, and the transformation theory, which he regards as the definitive form of quantum mechanics.

The book is considered a tour de force and remains indispensable for those interested in the fundamental issues of quantum mechanics.
