Abstract
To a braid we associate a complex of sheaves on such that the previously defined triply graded link homology of the closure is isomorphic to the homology of . The construction of relies on the Chern functor defined in the paper together with its adjoint functor . We prove a formula for the closure of sufficiently positive elements of the Jucys-Murphy algebra previously conjectured by Gorsky, Negut and Rasmussen.
