On the moduli spaces of parabolic symplectic orthogonal bundles on curves
Jianping Wang, Xueqing Wen
We prove that the moduli spaces of parabolic symplectic/orthogonal bundles on a smooth curve are globally F regular type. As a consequence, all higher cohomology of theta line bund…

Moduli Spaces of Homologically Trivial Parabolic (Higgs) Bundles on the Projective Line and an Application to the Deligne-Simpson Problem
Xueqing Wen
We establish an isomorphism between the moduli space of homologically trivial parabolic (Higgs) bundles on and the quiver variety associated to a star-shaped quiver.…
