Description

Functional integration successfully entered physics as path integrals in the 1942 PhD dissertation of Richard P.

Feynman, but it made no sense at all as a mathematical definition.

Cartier and DeWitt-Morette have created, in this book, a fresh approach to functional integration.

The book is self-contained: mathematical ideas are introduced, developed, generalised and applied.

In the authors' hands, functional integration is shown to be a robust, user-friendly and multi-purpose tool that can be applied to a great variety of situations, for example: systems of indistinguishable particles; Aharonov–Bohm systems; supersymmetry; non-gaussian integrals.

Problems in quantum field theory are also considered.

In the final part the authors outline topics that can be profitably pursued using material already presented.
