Abstract In this paper we study uncharged, non-conformal and anisotropic systems with strong interactions using the gauge-gravity duality by considering Einstein-Quadratic-Axion-Dilaton action in five dimension. In fact we would like to gain insight

Abstract The W(a, b) and $$W(a,b;\bar{a},\bar{b})$$ W ( a , b ; a ¯ , b ¯ ) algebras are deformations of $$\mathfrak {bms}_{3}$$ bms 3 and $$\mathfrak {bms}_{4}$$ bms 4 algebras, respectively. We present a $$\mathcal {N}=2$$ N = 2 supersymmetric e

Abstract We investigate the deformations and rigidity of boundary Heisenberg-like algebras. In particular, we focus on the Heisenberg and Heisenberg ⊕ witt $$ \mathfrak{witt} $$ algebras which arise as symmetry algebras in three-dimensional gravity

Abstract We present an interacting spin-2 gauge theory coupled to the two-dimensional dilaton-gravity in flat spacetime. The asymptotic symmetry group is enhanced to the central extension of Diff(S 1)⋉C ∞ (S 1)⋉Vec(S 1) when the central element

Abstract We present a three-dimensional Chern–Simons gravity based on a deformation of the Maxwell algebra. This symmetry allows introduction of a non-vanishing torsion to the Maxwell Chern–Simons theory, whose action recovers the Mielke–Baekle

Abstract In this work we present different infinite dimensional algebras which appear as deformations of the asymptotic symmetry of the three-dimensional Chern-Simons gravity for the Maxwell algebra. We study rigidity and stability of the infinite di

Abstract We continue analysis of [1] and study rigidity and stability of the b m s 4 $$ \mathfrak{b}\mathfrak{m}{\mathfrak{s}}_4 $$ algebra and its centrally extended version b m s 4 ^ $$ \widehat{\mathfrak{bm}{\mathfrak{s}}_4} $$ . We construct and

Abstract We study rigidity and stability of infinite dimensional algebras which are not subject to the Hochschild-Serre factorization theorem. In particular, we consider algebras appearing as asymptotic symmetries of three dimensional spacetimes, the
