Query: Frobenius inverse image of the semi-stable boundary in the moduli space
  of vector bundles   We study stable rank 2 vector bundles with trivial determinant whose
Frobenius pull back is non stable over a general curve of genus g>1. In genus
2, we apply recent results about the theta divisor associated to the bundle B
of locally exact differential forms and we derive a scheme-theoretic
description of the Frobenius inverse image of the semi-stable boundary of the
moduli space.
