Mathematics Association of IIT Bombay and Bombay Mathematical Colloquium

Speaker: Prof. P. Ramadevi
Affiliation:Physics Department, IIT Bombay
Title: Knots, Links and Three-dimensional Manifolds
Date: Friday, 19 September 2003
Time: 5.05 - 6.15 p. m.
Venue: Ramanujan Hall, II Floor.
Abstract
In this popular lecture, I will introduce basic ideas of Knot theory. It will be shown that several three dimensional manifolds can be constructed by a systematic process on knots/links embedded in a three sphere $S^3$. Edward Witten bagged the Fields Medal in 1989 for showing that a certain topological quantum field theory provides a natural framework for the study of knots and links. Thus study of certain theories in Physics provides an understanding of a class of Mathematical problems. I shall present one such theory called Chern-Simons theory and discuss its role in the theory of knots and three dimensional manifolds.
