Abstract

We study an AA_\infty category associated to Legendrian links in R3\mathbb{R}^3 whose objects are nn-dimensional representations of the Chekanov-Eliashberg differential graded algebra of the link. This representation category generalizes the positive augmentation category and we conjecture that it is equivalent to a category of sheaves of microlocal rank nn constructed by Shende, Treumann, and Zaslow. We establish the cohomological version of this conjecture for a family of Legendrian (2,m)(2,m) torus links.
