Analytic tangent cones of admissible Hermitian-Yang-Mills connections

Abstract

In this paper we study the analytic tangent cones of admissible Hermitian-Yang-Mills connections near a homogeneous singularity of a reflexive sheaf, and relate it to the Harder-Narasimhan-Seshadri filtration. We also give an algebro-geometric characterization of the bubbling set. This strengthens our previous result.

We improved the exposition of the paper based on the referees' suggestions
