Geometric action for extended Bondi-Metzner-Sachs group in four dimensions

open access: yesJournal of High Energy Physics, 2022
The constrained Hamiltonian analysis of geometric actions is worked out before applying the construction to the extended Bondi-Metzner-Sachs group in four dimensions.

Poisson convergence on the free Poisson algebra

open access: yes, 2015
Based on recent findings by Bourguin and Peccati, we give a fourth moment type condition for an element of a free Poisson chaos of arbitrary order to converge to a free (centered) Poisson distribution.

Novikov–Poisson Algebras

open access: yesJournal of Algebra, 1997
A Novikov algebra \(A\) is a vector space with an operation \(\circ \) satisfying the identities \[ (x\circ y)\circ z=(x\circ z)\circ y, \] \[ (x\circ y)\circ z - x\circ (y\circ z)=(y\circ x)\circ z - y\circ (x\circ z). \] A Novikov-Poisson algebra is a vector space \(A\) with two operations ``\(\cdot,\;\circ\)'' such that \((A,\cdot)\) forms a ...

Centralizers in free Poisson algebras [PDF]

open access: yesProceedings of the American Mathematical Society, 2007
We prove an analog of the Bergman Centralizer Theorem for free Poisson algebras over an arbitrary field of characteristic 0 0 . Some open problems are formulated.

Structures and Low Dimensional Classifications of Hom-Poisson Superalgebras

open access: yesAdvances in Mathematical Physics, 2015
Hom-Poisson superalgebras can be considered as a deformation of Poisson superalgebras. We prove that Hom-Poisson superalgebras are closed under tensor products. Moreover, we show that Hom-Poisson superalgebras can be described using only the twisting map

Metriplectic Algebra for Dissipative Fluids in Lagrangian Formulation

open access: yesEntropy, 2015
The dynamics of dissipative fluids in Eulerian variables may be derived from an algebra of Leibniz brackets of observables, the metriplectic algebra, that extends the Poisson algebra of the frictionless limit of the system via a symmetric semidefinite ...

Poisson Realization and Quantization of the Geroch Group

open access: yes, 1996
The conserved nonlocal charges generating the Geroch group with respect to the canonical Poisson structure of the Ernst equation are found. They are shown to build a quadratic Poisson algebra, which suggests to identify the quantum Geroch algebra with ...

Brane current algebras and generalised geometry from QP manifolds. Or, “when they go high, we go low”

open access: yesJournal 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 ...

Coadjoint Poisson actions of Poisson-Lie groups

open access: yes, 1999
A Poisson-Lie group acting by the coadjoint action on the dual of its Lie algebra induces on it a non-trivial class of quadratic Poisson structures extending the linear Poisson bracket on the coadjoint ...

Left-right noncommutative Poisson algebras [PDF]

open access: yesOpen Mathematics, 2014
AbstractThe notions of left-right noncommutative Poisson algebra (NPlr-algebra) and left-right algebra with bracket AWBlr are introduced. These algebras are special cases of NLP-algebras and algebras with bracket AWB, respectively, studied earlier. An NPlr-algebra is a noncommutative analogue of the classical Poisson algebra.
