Lecture notes (in progress; I'll update these when I can)Morse theory has historically served as an important intermediary between differential geometry and algebraic topology, and it has gained further importance in topology in the last few decades through the work of Floer, Witten, and many others. This minicourse will provide a rapid introduction to Morse theory with the goal of defining Morse homology. We'll then pivot to Floer homology, which can be thought of as an infinite-dimensional analogue of Morse homology, and discuss what's different in this setting.
I'll assume a basic familiarity with algebraic topology along the lines of Math 611 (people taking 611 concurrently should be fine). It may also be helpful to be comfortable with differential geometry along the lines of Math 633, but this isn't so necessary.
If you'd like further reading material, there are now many good books
on Morse theory and Morse homology, some with discussions of Floer
theory as well. These include:
