CANONICAL
PERTURBATION
THEORIES,
DEGENERATE SYSTEMS AND RESONANCE
I
thank my family for continuous support. Many friends and colleagues
have given
me suggestions that helped to improve the book.
I thank all of them and, particularly, Prof. Jean Kovalevsky,
who, long ago, introduced me to canonical perturbation theories and
Profs. André
Brahic, Rudolf Dvorak, Claude Froeschlé,
Juan Carlos Muzzio and Bruno Sicardy,
who have often invited me to their institutions, allowing me to have
time to write. I thank all my students.
They have read almost all
the drafts of this book and collaborated with valuable comments that
resulted
in many improvements in the written text. I thank the copy editor Mike
Nugent
for his invaluable contribution for the editorial quality of this book.
During
the work on this project, I had the support of USP --
