On Virasoro-type reductions and inverse Hamiltonian reductions for $W$ -algebras and $W_{\infty}$ -algebras

Justine Fasquel, Vladimir Kovalchuk, Shigenori Nakatsuka

In this article, the Virasoro-type reduction and the corresponding inverse reductions are established for W-algebras associated with classical Lie type and nilpotent orbits of heig…

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…

First-order deformations of freely generated vertex algebras

Vladimir Kovalchuk, Fei Qi

We solve the problem of how to classify the first-order vertex-algebraic deformations for any grading-restricted vertex algebra $V$ that is freely generated by homogeneous elements…
