Building blocks for $W$ -algebras of classical types

Thomas Creutzig, Vladimir Kovalchuk, Andrew R. Linshaw

The universal $2$ -parameter vertex algebra $W_{\infty}$ of type $W (2, 3, 4, \dots)$ serves as a classifying object for vertex algebras of type $W (2, 3, \dots, N)$ for some $N$ in the sen…

Minimal W-algebras of $so_{N}$ at level minus one

Thomas Creutzig, Justine Fasquel, Vladimir Kovalchuk +2

For $N \in Z_{\geq 7}$ we show that the simple minimal $W$ -algebra of $so_{N}$ at level minus one is isomorphic to the even subalgebra of the tensor produ…
