Knot Theory
The course is devoted to the modern knot theory.
The course starts with basic notions of Reidemeister moves, and proceeds with simplest invariants like colouring invariant, linking numbers, Kauffman bracket form of the Jones polynomial, Conway polynomial, which makes it accessible to students with no prerequisites.
Then it proceeds with basic invariants of knots such as fundamental group and the knot quandle, discusses braid theory (with Alexander and Markov theorem).
The course encompasses such deep constructions as Kontsevich integral and Khovanov homology (including Rasmussen invariant) and ends with author's personal results in this area.
We shall provide many problems: from exercises to unsolved problems in low-dimensional topology.
