The Picard group of the universal moduli stack of principal bundles on pointed smooth curves II
Roberto Fringuelli, Filippo Viviani
In this paper, which is a sequel of arXiv:2002.07494, we investigate, for any reductive group over an algebraically closed field , the Picard group of the universal moduli s…

On the Picard group scheme of the moduli stack of stable pointed curves
Roberto Fringuelli, Filippo Viviani
The aim of the present paper is to study the (abstract) Picard group and the Picard group scheme of the moduli stack of stable pointed curves over an arbitrary scheme. As a byprodu…

The Picard group of the universal moduli stack of principal bundles on pointed smooth curves
Roberto Fringuelli, Filippo Viviani
For any smooth connected linear algebraic group G over an algebraically closed field k, we describe the Picard group of the universal moduli stack of principal G-bundles over point…
