Representations are sheaves conjecture for Legendrian links

Let n1n\geq 1, let \mathbbmk\mathbbm{k} be a field, and let ΛR3\Lambda\subset\mathbb{R}^3 be a Legendrian link. The representation–sheaf conjecture. The AA_\infty category Repn(Λ,\mathbbmk)\mathcal{R}ep_n(\Lambda,\mathbbm{k}) of nn-dimensional representations of the Chekanov–Eliashberg differential graded algebra of Λ\Lambda is AA_\infty equivalent to the category Shn(Λ,\mathbbmk)\mathcal{S}h_n(\Lambda,\mathbbm{k}) of constructible sheaves with microsupport on Λ\Lambda and microlocal rank nn:

Repn(Λ,\mathbbmk)Shn(Λ,\mathbbmk).\mathcal{R}ep_n(\Lambda,\mathbbm{k})\stackrel{\sim}{\to}\mathcal{S}h_n(\Lambda,\mathbbm{k}).

This generalizes the known correspondence between the positive augmentation category and the sheaf category of microlocal rank one. The conjecture asks for the categorical correspondence for arbitrary representation dimension nn and remains unresolved in the supplied source.
