Tautological families of cyclic covers of projective spaces
Promit Kundu, Jayan Mukherjee, Debaditya Raychaudhury
In this article, we study the existence of tautological families on a Zariski open set of the coarse moduli space parametrizing certain Galois covers over projective spaces. More s…

On the Bogomolov-Gieseker inequality for tame Deligne-Mumford surfaces
Yunfeng Jiang, Promit Kundu, Hao Max Sun
We generalize the Bogomolov-Gieseker inequality for semistable coherent sheaves on smooth projective surfaces to smooth Deligne-Mumford surfaces. We work over positive characterist…
