Query: Motivic Donaldson-Thomas Invariants of Parabolic Higgs Bundles and
  Parabolic Connections on a Curve   Let $X$ be a smooth projective curve over a field of characteristic zero and
let $D$ be a non-empty set of rational points of $X$. We calculate the motivic
classes of moduli stacks of semistable parabolic bundles with connections on
$(X,D)$ and motivic classes of moduli stacks of semistable parabolic Higgs
bundles on $(X,D)$. As a by-product we give a criteria for non-emptiness of
these moduli stacks, which can be viewed as a version of the Deligne-Simpson
problem.
