The Selberg-Arthur Trace Formula

This book based on lectures given by James Arthur discusses
the trace formula of Selberg and Arthur. The emphasis is
laid on Arthur's trace formula for GL(r), with several
examples in order to illustrate the basic concepts. The book
will be useful and stimulating reading for graduate students
in automorphic forms, analytic number theory, and
non-commutative harmonic analysis, as well as researchers in
these fields. Contents:
