講義名　幾何学特論第一（Special Lectures on Geometry I）

【講義の目的】　(purpose of lectures)
In the last ten years, the introduction of Heegaard Floer homology lead to important advances in low-dimensional topology.
We will introduce this theory with particular attention to its implications in knot theory.
We will also discuss other recent, homology theory-valued knot invariants of a different nature:
these arise as categorifications of earlier knot polynomials.

【講義計画】　(course plan)
1.Morse homology on finite-dimensional closed manifolds
2.Alexander polynomial
3.Heegaard Floer homology, including knot Floer homology and sutured Floer homology
4.Jones and Homfly polynomials 5. Khovanov and Khovanov--Rozansky homology

Based on a small number of homework problems and participation.

【担当教員から一言】　(comments)
Rather than addressing deep analytic issues, the emphasis will be on applications of the techniques.
Many examples will be included.
