Titre |
Nilpotent Slodowy slices and W-algebras |
|
Résumé |
To any vertex algebra one can attach in a canonical way a certain Poisson variety,
called the associated variety. Nilpotent Slodowy slices appear as associated
varieties of admissible (simple) W-algebras. They also appear as Higgs branches of
the Argyres-Douglas theories in 4d N=2 SCFT’s. These two facts are linked by the
so-called Higgs branch conjecture. In this talk I will explain how to exploit the
geometry of nilpotent Slodowy slices to study some properties of W-algebras whose
motivation stems from physics. This is a joint work with Tomoyuki Arakawa and
Jethro van Ekeren (still in preparation). |
