It is a surprising fact that so far almost no books have been published
on KAM theory. The first part of this book seems to be the first
monographic exposition of this subject, despite the fact that the
discussion of KAM theory started as early as 1954 (Komogorov) and was
developed later in 1962 by Arnold and Moser. Today, this mathematical
field is very popular and well known among physicists and
mathematicians.
