Abstract

Let X be a smooth complex projective variety of dimension n and L an ample line bundle on it. There is a well known bijective correspondence between the isomorphism classes of polystable vector bundles E on X with c1 (E) = 0 = c2 (E) . c1 (L) n-2 and the equivalence classes of unitary representations of π 1 (X). We show that this bijective correspondence extends to smooth orbifolds.
