Tobias Metzlaff (TU Kaiserslautern) - Symplectic singularities and diagonal invariants
10h30-11h30
9 November 2023
Symplectic singularities were introduced by Beauville in 2000 to extend the notion of smoothness to the singular world of symplectic forms. Next to their intriguing geometric properties, they arise naturally in Lie theory, where they establish a link between commutative algebraic geometry and noncommutative representation theory. In this talk, I will highlight some computational aspects that boil down to the calculation of fundamental invariants for certain group actions, which are known due to Haiman as diagonal invariants.
