Universal compactified Jacobians: cohomological invariance and boundary combinatorics

Abstract Pagani and Tommasi have introduced a class of smoothable fine compactified Jacobians $$\overline{\mathcal {J}}_{g,n}^{\,d}(\sigma )\rightarrow \overline{\mathcal {M}}_{g,n}$$ J ¯ g , n d ( σ ) → M ¯ g , n over the moduli space of stable curves, depending nontrivially on...
