Abstract

We study the relation between augmentations and sheaves in the context of framed oriented links. In this set up, we find slightly more sheaves than augmentations. After removing the sporadic sheaves, we construct a bijective correspondence between augmentations of the framed cord algebra and simple sheaves that are micro-supported along the conormal bundle of the link.
