Irreducible symplectic 4-folds and Eisenbud-Popescu-Walter sextics
Kieran G. O'Grady
Eisenbud Popescu and Walter have constructed certain special 4-dimensional sextic hypersurfaces as Lagrangian degeneracy loci. We prove that the natural double cover of a generic E…
Irreducible symplectic 4-folds numerically equivalent to Hilb^2(K3)
Kieran G. O'Grady
First steps towards a classification of irreducible symplectic 4-folds whose integral 2-cohomology with 4-tuple cup product is isomorphic to that of Hilb^2(K3). We prove that any s…
A new six dimensional irreducible symplectic variety
Kieran G. O'Grady
By results of the author there exists a projective (holomorphic) symplectic desingularization of the moduli space of rank-two torsion-free sheaves on a genus-two Jacobian with $c_1…
Desingularized moduli spaces of sheaves on a K3, II
Kieran G. O'Grady
In preprint alg-geom/9708009 we have constructed a (ten-dimensional) symplectic desingularization of the moduli space of rank-two torsion-free semistable sheaves on a , with tr…
