This is the second, significantly expanded
edition of the comprehensive textbook
of 1990 on the theory and applications
of path integrals. It is the first book
to explicitly solve path integrals of
a wide variety of nontrivial
quantum-mechanical systems, in particular
of the hydrogen atom.
The solutions have been made possible

The first is a new euclidean path integral formula
which increases the restricted

The second is a simple quantum equivalence principle

The Chern-Simons theory of particles with fractional statistics ( anyons)
