(Chiral) Virasoro invariance of the tree-level MHV graviton scattering amplitudes
Journal of High Energy Physics, 2022 In this paper we continue our study of the tree level MHV graviton scattering amplitudes from the point of view of celestial holography. In arXiv:2008.04330 we showed that the celestial OPE of two gravitons in the MHV sector can be written as a linear ...

Soft charges and electric-magnetic duality
Journal of High Energy Physics, 2018 The main focus of this work is to study magnetic soft charges of the four dimensional Maxwell theory. Imposing appropriate asymptotic falloff conditions, we compute the electric and magnetic soft charges and their algebra both at spatial and at null ...

Extensions of the asymptotic symmetry algebra of general relativity
Journal of High Energy Physics, 2020 We consider a recently proposed extension of the Bondi-Metzner-Sachs algebra to include arbitrary infinitesimal diffeomorphisms on a 2-sphere. To realize this extended algebra as asymptotic symmetries, we work with an extended class of spacetimes in ...

Diffeomorphisms as quadratic charges in 4d BF theory and related TQFTs
Journal of High Energy Physics, 2023 We present a Sugawara-type construction for boundary charges in 4d BF theory and in a general family of related TQFTs. Starting from the underlying current Lie algebra of boundary symmetries, this gives rise to well-defined quadratic charges forming an ...

CURRENT ALGEBRA AND η→ 3π [PDF]
Nuclear Physics B, 1968 Abstract A critical review is given of developments in the theory subsequent to the demonstration that in first approximation η → 3 π is forbidden. It remains difficult to understand the process with conventional ideas without reducing to an accident the success of current algebra, and a simple linear matrix element, in K → 3 π .

CURRENT ALGEBRA FUNCTORS AND EXTENSIONS [PDF]
Reviews in Mathematical Physics, 2013 We show how the fundamental cocycles on current Lie algebras and the Lie algebra of symmetries for the sigma model are obtained via the current algebra functors introduced in [A. Alekseev and P. Severa, Equivariant cohomology and current algebras, Confluentes Math.4 (2012) 1250001, 40 pp.]. We present current group extensions integrating some of these

Journal of High Energy Physics, 2021 We construct a Poisson algebra of brane currents from a QP-manifold, and show their Poisson brackets take a universal geometric form. This generalises a result of Alekseev and Strobl on string currents and generalised geometry to include branes with ...

Weyl Pair, Current Algebra and Shift Operator [PDF]
, 1994 The Abelian current algebra on the lattice is given from a series of the independent Weyl pairs and the shift operator is constructed by this algebra. So the realization of the operators of the braid group is obtained.

A New Current Algebra and the Reflection Equation [PDF]
, 2009 We establish an explicit algebra isomorphism between the quantum reflection algebra for the $${U_q(\widehat{sl_2}) R}$$-matrix and a new type of current algebra.
