Abstract

Hyperkähler manifolds play a crucial role in Mathematics and Physics. They appear for instance in General Relativity as solutions spaces of Einstein equations, or in Quantum Field Theory in the study of Yang--Mills equations.One of the goals of the current project is the development of the theory of singular irreducible symplectic varieties (which could be seen as the singular case of hyperkähler manifolds). In particular we expect important improvements of this theory from the study of the Beauville--Bogomolov form and the periodic map.Another important aspect of hyperkähler geometry is the study of moduli spaces of semistable sheaves on hyperkähler manifolds. We hope to produce new examples of irreducible symplectic varieties by studying moduli spaces of sheaves, like Quot schemes, on K3 surfaces. (AU)
