We study O'Grady examples of irreducible symplectic varieties: we establish that both of them can be deformed into lagrangian fibrations. We analyze in detail the topology of the six dimensional example: in particular we compute its Euler characteristic and determine its Beauville form.

Abstract
We study O'Grady examples of irreducible symplectic varieties: we establish that both of them can be deformed into lagrangian fibrations. We analyze in detail the topology of the six dimensional example: in particular we compute its Euler characteristic and determine its Beauville form.File in questo prodotto:
