On the Perversity of Chern Classes for Compactified Jacobians

Published 5 Aug 2025 in math.AG | (2508.03103v1)

Abstract: We prove some perversity bounds for the Chern classes of a compactified Jacobian fibration, namely the $k$-th Chern class of the compactified Jacobian has perversity $\leq k$. Our results are motivic in nature, and we also prove a filtration version of a conjecture raised in arxiv:2402:08861.
