Title: Nilpotent orbits arising from admissible affine vertex algebras

Abstract: In this talk, I will give a simple description of the closure of the nilpotent orbits appearing as associated varieties of admissible affine vertex algebras in terms of primitive ideals. I will also connect these varieties with the cohomology of the small quantum groups associated with an l-th root of unity..
