Motivic Donaldson-Thomas Invariants of Parabolic Higgs Bundles and Parabolic Connections on a Curve

Let be a smooth projective curve over a field of characteristic zero, and let be a non-empty set of rational points of . We calculate the motivic classes of moduli stacks of semistable parabolic bundles with connections on (, ) and the motivic classes of moduli stacks of semistable parabolic Higgs...

description Let be a smooth projective curve over a field of characteristic zero, and let be a non-empty set of rational points of . We calculate the motivic classes of moduli stacks of semistable parabolic bundles with connections on (, ) and the motivic classes of moduli stacks of semistable parabolic Higgs bundles on (, ). As a by-product, we give a criterion for the non-emptiness of these moduli stacks, which can be viewed as a version of the Deligne-Simpson problem.
