Gandalf (Pure Maths Student Seminar): On the Khovanov Homotopy Type

Presented by Dan Jones, Durham

20 March 2014 16:00 in CM219

In 2000, Khovanov introduced a knot invariant in the form of a homology theory now known as Khovanov Homology. I will introduce this invariant and go on to talk about a new knot invariant which takes the form of a suspension spectrum, and so is invariant up to stable homotopy. The Khovanov Spectrum was introduced by Lipshitz and Sarkar in 2011 and has been shown to be a stronger invariant than Khovanov Homology. I aim to discuss some questions I have been looking at related to this spectrum.
