Modules of the Temperley-Lieb algebra at zero

Abstract

We explicitly describe the category of modules of the Temperley-Lieb algebra TLn(β)\mathrm{TL}_n(\beta) under specialization β=0\beta=0 for even nn in terms of a quiver algebra, analogous to a result of Berest-Etingof-Ginzburg. In particular, we explicitly construct an exact sequence of the standard modules of TLn(0)\mathrm{TL}_n(0), which categorifies a numerical coincidence regarding the evaluation of the Jones polynomial at t=1t=-1. We furthermore deduce a consequence in the representation theory of symmetric groups over characteristic two.
