Course description and aims
We will cover important subjects in low-dimensional geometric topology, such as knots, links, three-manifolds, the Alexander polynomial, and Morse theory, all with a view toward developing Floer homology. Floer homology is central to modern topology and related fields, with many manifestations. In this course we concentrate on Heegaard Floer homology and its applications.
Student learning outcomes
We aim to prepare students for research in low-dimensional topology.
Keywords
knots, links, three-manifolds, Alexander polynomial, genus and fibredness, Morse theory, Floer homology

Out-of-Class Study Time (Preparation and Review)
To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class contents afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
Textbook(s)
none
Reference books, course materials, etc.
Survey papers by Juhasz (arXiv:1310.3418) and Manolescu (http://arxiv.org/abs/1401.7107), plus online lecture notes by Hutchings (http://math.berkeley.edu/~hutching/teach/276-2010/mfp.ps).
