Title: On a conjecture of Drinfeld.
Abstract: Let C be a smooth irreducible projective curve of genus g ≥ 4.
Let MC(r, δ) be moduli space of stable vector bundles on C of rank r and
fixed determinant δ of degree d. Then the locus of wobbly bundles is known
to be closed in MC(r, δ). Drinfeld has conjectured that the wobbly locus is
pure of co-dimension one, i.e. it is a divisor in MC(r, δ). In this talk,
we will give proof of the conjecture when (r, d) = 1
