Under numerical assumptions, connected components of moduli spaces of modular vector bundles on K3^{[n]}-type IHS manifolds are again IHS manifolds of K3^{[n]}-type and induce derived equivalences with the original manifolds.

Moduli spaces of slope-stable projective bundles on K3^[2]-type HK manifolds yield normalizations that are K3^[a^2+1]-type HK manifolds, with converse and induced rational Hodge isometries.
Constructs irreducible symplectic varieties of dimension 2n (2≤n≤10) with 16≤b2≤24 as non-trivial terminalisations of finite symplectic quotients of Beauville-Mukai systems on very general K3-del Pezzo double covers.
Brauer groups of smooth loci in linear systems are bounded by Z/2Z under ampleness, with application to computing Tate-Shafarevich groups for Jacobians of plane curves.
Constructs Poincaré sheaf on compactified Prym varieties for singular curves and proves Fourier-Mukai autoequivalence, with applications to motivic decomposition and perverse filtrations.
