We review a geometrical approach to the description of the dynamics of superparticles,
superstrings and, in general, of super-p-branes, Dirichlet branes and the M5-brane, which is …

In this paper it is stressed that there is no physical reason for symmetries to be linear and
that Lie group theory is therefore too restrictive. We illustrate this with some simple …

We discuss how to systematically compute the asymptotic symmetry algebras of generic
three-dimensional bosonic higher-spin gauge theories in backgrounds that are …

Abstract Two-dimensional {sl}(n) quantum Toda field theory on a sphere is considered. This
theory provides an important example of conformal field theory with higher spin symmetry …

We investigate systematically the asymptotic dynamics and symmetries of all three-
dimensional extended AdS supergravity models. First, starting from the Chern–Simons …

A bstract We indicate how to introduce chemical potentials for higher spin charges in higher
spin anti-de Sitter gravity in a manner that manifestly preserves the original asymptotic W …

A bstract The asymptotic dynamics of AdS 3 gravity with two asymptotically anti-de Sitter
regions is investigated, paying due attention to the zero modes, ie, holonomies along non …

Abstract Recently Alday and Tachikawa [1] proposed a relation between conformal blocks in
a two-dimensional theory with affine sl (2) symmetry and instanton partition functions in four …

We construct several quantum coset algebras, eg and and argue that they are finitely
nonfreely generated. Furthermore, we discuss in detail their role as unifying algebras of …

A bstract We study the operator product expansions in the chiral algebra\({\mathcal {W}} _
{\infty}\), first using the associativity conditions in the basis of primary generating fields and …
