Ito's conjecture and the coset construction for
Naoki Genra, Andrew R. Linshaw
Many -(super)algebras which are defined by the generalized Drinfeld-Sokolov reduction are also known or expected to have coset realizations. For example, it was conje…

Singular support of a vertex algebra and the arc space of its associated scheme
Tomoyuki Arakawa, Andrew R. Linshaw
Attached to a vertex algebra are two geometric objects. The associated scheme of is the spectrum of Zhu's Poisson algebra . The singula…
