Bounds on generators and relations for the algebra of $SL_2(\C)$   conformal blocks
  We show that the Cox ring of the moduli of $SL_2(\C)$ quasi-parabolic principal bundles on a marked curve is generated by conformal blocks of level 1 and 2. We show that the ideal which vanishes on these generators is generated by forms of degrees $2, 3, 4.$
