Universal compactified Jacobians: cohomological invariance and boundary combinatorics
Rahul Pandharipande, Dan Petersen, Johannes Schmitt +1
The paper gives a direct combinatorial proof that the cohomology of universal compactified Jacobians over the moduli space of stable curves does not depend on the degree or the cho…

The low degree cohomology of compactifications of
Samir Canning, Dan Petersen, Olivier Taïbi
We compute the low degree -adic intersection cohomology of symplectic local systems on the Satake compactification of the moduli space of principally polarized abelian…
