In recent years scholars from a variety of branches of mathematics have
made several significant developments in the theory of group actions.
Groups of Circle Diffeomorphisms systematically explores group actions
on the simplest closed manifold, the circle. As the group of circle
diffeomorphisms is an important subject in modern mathematics, this book
will be of interest to those doing research in group theory, dynamical
systems, low dimensional geometry and topology, and foliation theory.
The book is mostly self-contained and also includes numerous
complementary exercises, making it an excellent textbook for
undergraduate and graduate students.
