MaPSS: Maths Postgraduate Seminar Series: Hazel Browne -- Singular Knots and Finite Type Invariants

Hello all, 

The next MaPSS talk of this semester will be at 17:00 on Mon 3rd September in Carslaw
535.  It’s a great opportunity to meet fellow postgrads, listen to an interesting
talk, and of course get free food!

Speaker: Hazel Browne

Title: Singular Knots and Finite Type Invariants 

Abstract: Does the question of how to tell knots apart keep you awake at night? Have
you ever wondered whether a lot of the common knot invariants can be better understood
when considering their values on resolutions of singular knots?

If so, Finite Type Invariants may be just what you need.

In this talk, we will introduce singular knots and explain how they give a filtration
on the vector space spanned by knots. We will use this to give a definition of Finite
Type Invariants and look at a few examples. Finally, we will explain how we can
construct Finite Type Invariants using Lie algebraic information.
