Gandalf (Pure Maths Student Seminar): Virtual Khovanov Homology

Presented by Will Rushworth, Durham

11 November 2015 16:00 in CM221

Khovanov homology is a chain-complex valued invariant of links. Virtual knot theory is a generalisation of classical knot theory which considers embeddings of circles into thickened surfaces of genus g>0 (the g=0 case returns classical knot theory). We give an introduction to virtual knots and a quick overview of the definition of Khovanov homology, before going through the process of a generalising it to the virtual case in a picture-heavy and pedagogical way.
