TITLE: Looking for a good book on Morse-Bott functions.
QUESTION [7 upvotes]: I am looking for a book to study for the first time Morse-Bott functions. Does anyone know one that is easy to follow and detailed? If there is one connecting this subject with symplectic geometry, it would be useful too.
Thanks!

REPLY [6 votes]: The article Cascades and perturbed Morse-Bott functions by A. Banyaga and D. Hurtubise is quite nice and relatively easy to read. Other useful references are:

Morse-Bott theory and equivariant cohomology by D.M. Austin and P.J. Braam. It appears in the Floer memorial volume.
Appendix C of Urs Frauenfelder's PhD thesis, especially in connection with Floer-theory.
Appendix A of The Arnold-Givental conjecture and moment Floer homology by Urs Frauenfelder.

I think that all of these references relate Morse-Bott theory to symplectic geometry and in particular to Floer-theory.
