Universal compactified Jacobians: cohomological invariance and boundary combinatorics

Rahul Pandharipande, Dan Petersen, Johannes Schmitt +1

Pagani and Tommasi have introduced a class of smoothable fine compactified Jacobians ${\overline{\mathcal{J}}}_{g,n}^d(\sigma )\to {\overline{\mathcal{M}}}_{g,n}$ over the moduli spa…
