Abstract We show that there are four chiral W $$ \mathcal{W} $$ -algebra extensions of so 2 3 $$ \mathfrak{so}\left(2,3\right) $$ algebra and construct them explicitly. We do this by a simple identification of each of the inequivalent embeddings of a

Generalising the chiral boundary conditions of R1,3 gravity for AdS4 gravity, we derive chiral locally AdS4 solutions in the Newman-Unti gauge consistent with a variational principle whose asymptotic symmetry algebra we show, to be an infinite-dimens

Abstract We construct classical theories for scalar fields in arbitrary Carroll spacetimes that are invariant under Carrollian diffeomorphisms and Weyl transformations. When the local symmetries are gauge fixed these theories become Carrollian confor

Abstract We study singular time-dependent 1 8 $$ \frac{1}{8} $$ -BPS configurations in the abelian sector of N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory that represent BPS string-like defects in ℝ × S 3 spacetime. Such BPS strings can

Abstract We study asymptotic symmetry algebras for classes of three dimensional supergravities with and without cosmological constant. In the first part we generalise some of the non-dirichlet boundary conditions of AdS 3 gravity to extended supergra

Abstract In this paper we continue to develop further our prescription [ arXiv:1602.02962 ] to holographically compute the conformal partial waves of CFT correlation functions using the gravitational open Wilson network operators in the bulk. In part

We study singular time-dependent $\frac{1}{8}$-BPS configurations in the abelian sector of ${{\mathcal N}= 4}$ supersymmetric Yang-Mills theory that represent BPS string-like defects in ${{\mathbb R}\times S^3}$ spacetime. Such BPS strings can be des
