Physics Letters B, 2008 A 3-bracket variant of the Virasoro-Witt algebra is constructed through the use of su(1,1) enveloping algebra techniques. The Leibniz rules for 3-brackets acting on other 3-brackets in the algebra are discussed and verified in various situations.

Approximate symmetries in d = 4 CFTs with an Einstein gravity dual
Journal of High Energy Physics, 2022 By applying the stress-tensor-scalar operator product expansion (OPE) twice, we search for algebraic structures in d = 4 conformal field theories (CFTs) with a pure Einstein gravity dual.

European Physical Journal C: Particles and Fields, 2018 By means of the Lie algebra expansion method, the centrally extended conformal algebra in two dimensions and the $$\mathfrak {bms}_{3}$$ bms3 algebra are obtained from the Virasoro algebra.

W algebra and eigenvalues of the low-order string constraint operators for the discrete KP hierarchy
Partial Differential Equations in Applied Mathematics, 2022 Firstly, for any p∈N, the string constraint operators without the redundant variables are calculated, which are imposed by the string equation on the τ-function of the p-reduced discrete Kadomtsev–Petviashvili (dKP) hierarchy.

Loop Virasoro Lie conformal algebra [PDF]
Journal of Mathematical Physics, 2014 The Lie conformal algebra of loop Virasoro algebra, denoted by \documentclass[12pt]{minimal}\begin{document}$\mathscr {CW}$\end{document}CW, is introduced in this paper. Explicitly, \documentclass[12pt]{minimal}\begin{document}$\mathscr {CW}$\end{document}CW is a Lie conformal algebra with \documentclass[12pt]{minimal}\begin{document}$\mathbb {C ...

Surface charges in Chern-Simons gravity with T T ¯ $$ T\overline{T} $$ deformation
Journal of High Energy Physics, 2022 The T T ¯ $$ T\overline{T} $$ deformed 2D CFTs correspond to AdS3 gravity with Dirichlet boundary condition at finite cutoff or equivalently a mixed boundary condition at spatial infinity.

Virasoro symmetries of the constrained dispersionless mKP hierarchy
Physics Letters B, 2023 This paper aims at the auto-Bäcklund transformations for the dispersionless mKP hierarchy, dispersionless Miura map between the constrained dispersionless mKP hierarchy and the constrained dispersionless Harry Dym hierarchy and Virasoro symmetries of the

Entropy of a generic null surface from its associated Virasoro algebra
Physics Letters B, 2016 Null surfaces act as one-way membranes, blocking information from those observers who do not cross them (e.g., in the black hole and the Rindler spacetimes) and these observers associate an entropy (and temperature) with the null surface.
