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…

On the P=W conjecture for

Mark Andrea A. de Cataldo, Davesh Maulik, Junliang Shen

Let be a prime number. We prove that the conjecture for is equivalent to the conjecture for . As a consequence, we verify the c…

P=W for Lagrangian fibrations and degenerations of hyper-Kähler manifolds

Andrew Harder, Zhiyuan Li, Junliang Shen +1

We identify the perverse filtration of a Lagrangian fibration with the monodromy weight filtration of a maximally unipotent degeneration of compact hyper-Kähler manifolds.

Topology of Lagrangian fibrations and Hodge theory of hyper-Kähler manifolds

Junliang Shen, Qizheng Yin

We establish a compact analog of the P = W conjecture. For a holomorphic symplectic variety with a Lagrangian fibration, we show that the perverse numbers associated with the fibra…

Perverse filtrations, Hilbert schemes, and the P=W conjecture for parabolic Higgs bundles

Junliang Shen, Zili Zhang

We prove de Cataldo-Hausel-Migliorini's P=W conjecture in arbitrary rank for parabolic Higgs bundles labeled by the affine Dynkin diagrams , , $\tilde{E}_…

Rational curves in holomorphic symplectic varieties and Gromov-Witten invariants

Georg Oberdieck, Junliang Shen, Qizheng Yin

We use Gromov-Witten theory to study rational curves in holomorphic symplectic varieties. We present a numerical criterion for the existence of uniruled divisors swept out by ratio…
