Query: The Essential Dimension of Stacks of Parabolic Vector Bundles over
  Curves   We find upper bounds on the essential dimension of the moduli stack of
parabolic vector bundles over a curve. When there is no parabolic structure, we
improve the known upper bound on the essential dimension of the usual moduli
stack. Our calculations also give lower bounds on the essential dimension of
the semistable locus inside the moduli stack of vector bundles of rank $r$ and
degree $d$ without parabolic structure.
