Pullbacks of universal Brill-Noether classes via Abel-Jacobi morphisms

Nicola Pagani, Andrea T. Ricolfi, Jason van Zelm

Following Mumford and Chiodo, we compute the Chern character of the derived pushforward $\text{ch}(R^{\bullet }{\pi }_{\ast }\mathcal{O}(\mathsf{D}))$, for $\mathsf{D}$ an arbitrary element…
