Birational geometry of Beauville-Mukai systems III: asymptotic behavior

Xuqiang Qin, Justin Sawon

Suppose that a Hilbert scheme of points on a K3 surface S of Picard rank one admits a rational Lagrangian fibration. We show that if the degree of the surface is sufficiently large…

Birational geometry of Beauville-Mukai systems II: general theory in low ranks

Xuqiang Qin, Justin Sawon

Via wall-crossing, we study the birational geometry of Beauville-Mukai systems on K3 surfaces with Picard rank one. We show that there is a class of walls which are always present…

Birational geometry of Beauville-Mukai systems I: the rank three and genus two case

Xuqiang Qin, Justin Sawon

We study wall-crossing for the Beauville-Mukai system of rank three on a general genus two K3 surface. We show that such a system is related to the Hilbert scheme of ten points on…

Topological bounds on hyperkähler manifolds

Justin Sawon

We conjecture that certain curvature invariants of compact hyperkähler manifolds are positive/negative. We prove the conjecture in complex dimension four, give an "experimental pro…

Deformations of compact Prym fibrations to Hitchin systems

Justin Sawon, Chen Shen

We describe certain Lagrangian fibrations by Prym varieties on holomorphic symplectic varieties that deform to compactifications of Sp-Hitchin systems.

Singular fibres of very general Lagrangian fibrations

Justin Sawon

Let be a (holomorphic) Lagrangian fibration that is very general in the moduli space of Lagrangian fibrations. We conjecture that the singular fibres i…
