Moduli Spaces of Parabolic Bundles over $\mathbb{P}^1$ with Five Marked Points

Abstract: This paper considers the moduli spaces (stacks) of parabolic bundles (parabolic logarithmic flat bundles with given spectrum, parabolic regular Higgs bundles) with rank 2 and degree 1 over $\mathbb{P}<sup>1$ with five marked points. The foliation and stratification structures on these moduli spaces (stacks) are investigated. In particular, we confirm Simpson's conjecture for moduli space of parabolic logarithmic flat bundles with certain non-special weight system.
