DESCRIPTION:Co-Author: Xuemiao Chen (Stony Brook)
The D
onaldson-Uhlenbeck-Yau theorem relates the existen
ce of \;Hermitian-Yang-Mills connection \;
over a compact Kahler manifold with algebraic 
\;stability of a \;holomorphic vector bundle.
This has been extended by Bando-Siu to the case of
reflexive sheaves\, and the corresponding connect
ion may have \;singularities. We study tangent
cones around such a singularity\, which is define
d in the usual geometric analytic way\, \;&nbs
p\;and relate it to the Harder-Narasimhan-Seshadri
filtration of a suitably defined torsion free she
af on the projective space\, which is a purely alg
ebro-geometric object. \;
