New universal vertex algebras as glueings of the basic ones
Thomas Creutzig, Vladimir Kovalchuk, Andrew R. Linshaw
There are three universal -parameter vertex algebras , , and which are freely gene…
Minimal W-algebras of at level minus one
Thomas Creutzig, Justine Fasquel, Vladimir Kovalchuk +2
For we show that the simple minimal -algebra of at level minus one is isomorphic to the even subalgebra of the tensor produ…
On Virasoro-type reductions and inverse Hamiltonian reductions for -algebras and -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 -algebras of classical types
Thomas Creutzig, Vladimir Kovalchuk, Andrew R. Linshaw
The universal -parameter vertex algebra of type serves as a classifying object for vertex algebras of type for some 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 that is freely generated by homogeneous elements…
Generalized parafermions of orthogonal type
Thomas Creutzig, Vladimir Kovalchuk, Andrew R. Linshaw
There is an embedding of affine vertex algebras , and the coset $\mathcal{C}^k(n) = \text{Com}(V^k(\mathfrak{gl}_n),…
