Dualizable abelian fibrations

Davesh Maulik, Junliang Shen, Qizheng Yin

In his proof of the fundamental lemma of the Langlands program, Ngô initiated the study of the decomposition theorem for abelian fibrations. When an abelian fibration admits a dual…

On the Orlov conjecture for hyper-Kähler varieties via hyperholomorphic bundles

Davesh Maulik, Junliang Shen, Qizheng Yin

We study Fourier transforms induced by Markman's projectively hyperholomorphic bundles on products of hyper-Kähler varieties of -type. As applications, we prove the follo…

The intrinsic cohomology ring of the universal compactified Jacobian over the moduli space of stable curves

Younghan Bae, Davesh Maulik, Junliang Shen +1

The purpose of this paper is to study the cohomology rings of universal compactified Jacobians. Over the moduli space of Deligne-Mumford stable marke…

The period-index problem for hyper-Kähler varieties via hyperholomorphic bundles

James Hotchkiss, Davesh Maulik, Junliang Shen +2

We prove new bounds for the period-index problem for hyper-Kähler varieties of -type using projectively hyperholomorphic bundles constructed by Markman. We show that $\ma…

On intersection cohomology and Lagrangian fibrations of irreducible symplectic varieties

Camilla Felisetti, Junliang Shen, Qizheng Yin

We prove several results concerning the intersection cohomology and the perverse filtration associated with a Lagrangian fibration of an irreducible symplectic variety. We first sh…

Motivic decompositions for the Hilbert scheme of points of a K3 surface

Andrei Neguţ, Georg Oberdieck, Qizheng Yin

We construct an explicit, multiplicative Chow-Künneth decomposition for the Hilbert scheme of points of a K3 surface. We further refine this decomposition with respect to the actio…
