The CRT working group will meet again this Friday at 3.30pm in Carslaw 159, as usual. Abstract appears below, hope to see you there! Khovanov’s categorification of the Weyl algebra ----- The Weyl algebra is the ring of univariate differential operators with polynomial coefficients. In 2001, Khovanov published a categorification of the defining representation of the Weyl algebra on the polynomial ring, using the so-called nilCoxeter algebras. In this talk, we’ll review the categorification, hopefully covering the Leibnitz rule and integration as anti-differentiation.
