Moduli spaces of framed logarithmic and parabolic connections on a Riemann surface
arXiv:2504.00931 · doi:10.1112/mod.2025.5
Abstract
We construct moduli spaces of framed logarithmic connections and also moduli spaces of framed parabolic connections. It is shown that these moduli spaces possess a natural algebraic symplectic structure. We also give an upper bound of the transcendence degree of the algebra of regular functions on the moduli space of parabolic connections.
