Algebra Seminar: Wedrich -- Extremal weight projectors and categorification of skein algebras

Paul Wedrich (ANU) 

Friday 27 October, 2:30-3:30pm, Place: Carslaw 375 

Title: Extremal weight projectors and categorification of skein algebras 

Abstract: The Temperley-Lieb algebra gives a diagrammatic presentation of the
representation category of quantum sl(2), with the famous Jones-Wenzl projectors
encoding projections onto finite-dimensional irreducibles.  I will talk about a related
diagrammatic calculus, in which the Jones-Wenzl projectors decompose further into
’’extremal weight projectors’’, and then explain how this might help to categorify skein
algebras using link homology technology as developed by Khovanov and others.  This is
joint work with Hoel Queffelec.
