Chen-Ruan cohomology and moduli spaces of parabolic bundles over a Riemann surface

Indranil Biswas, Pradeep Das, Anoop Singh

Let $(X, D)$ be an $m$ -pointed compact Riemann surface of genus at least $2$ . For each $x \in D$ , fix full flag and concentrated weight system $α$ . Let $P M_{ξ}$ denot…

On the relative logarithmic connections and relative residue formula

Snehajit Misra, Anoop Singh

We investigate the relative logarithmic connections on a holomorphic vector bundle over a complex analytic family. We give a sufficient condition for the existence of a relative lo…

A note on the moduli spaces of holomorphic and logarithmic connections over a compact Riemann surface

Anoop Singh

Let $X$ be a compact Riemann surface of genus $g \geq 3$ . We consider the moduli space of holomorphic connections over $X$ and the moduli space of logarithmic connections singular…
