讲座题目：Introduction to Knot theory and some related topics (20学时,10次)
讲座摘要：This is an introductory course in Knot Theory. The theory started in the 19th century with naive tables of knots, i.e. continuous loops in the space. At present knot theory is a wide area of mathematics having deep relations with front lines of topology, geometry, algebra, combinatorics, theoretical physics and DNA. This areas has a specialized mathematical journal - Journal of Knot Theory and Its Ramifications.
In the class we will discuss basic ideas and classical theorems. We will construct various invariants and use them to distinguish knots. We will complete the course with modern ideas and results.
