Conformal invariance in quantum field theory

The present volume is an extended and up-to-date version of two sets of lectures by the first author and it reviews more recent work. Other parts in application of the conformal group to quantum physics are only briefly mentioned.

The present volume is an extended and up-to-date version of two sets of lectures by the first author and it reviews more recent work. The notes aim to present a self-contained exposition of a constructive approach to conformal invariant quantum field theory. Other parts in application of the conformal group to quantum physics are only briefly mentioned. The relevant mathematical material (harmonic analysis on Euclidean conformal groups) is briefly summarized. A new exposition of physical applications is given, which includes an explicit construction of the vacuum operator product expansion for the free zero mass fields.
