On deformations and extensions of $Diff (S^{2})$

Martin Enriquez-Rojo, Tomáš Procházka, Ivo Sachs

We investigate the algebra of vector fields on the sphere. First, we find that linear deformations of this algebra are obstructed under reasonable conditions. In particular, we sho…

The Grassmannian VOA

Lorenz Eberhardt, Tomáš Procházka

We study the 3-parametric family of vertex operator algebras based on the unitary Grassmannian coset CFT $u (M + N)_{k} / (u (M)_{k} \times u (N)_{k})$ . This VO…

On even spin $W_{\infty}$

Tomáš Procházka

We study the even spin $W_{\infty}$ which is a universal $W$ -algebra for orthosymplectic series of $W$ -algebras. We use the results of Fateev and Lukyan…

$W$ -algebra Modules, Free Fields, and Gukov-Witten Defects

Tomáš Procházka, Miroslav Rapčák

We study the structure of modules of corner vertex operator algebras arrising at junctions of interfaces in $N = 4$ SYM. In most of the paper, we concentrate on truncations…
