Residual gauge symmetry in light-cone electromagnetism
Journal of High Energy Physics, 2023 We analyze the residual gauge freedom in light-cone electromagnetism in four dimensions. The standard boundary conditions involved in the so-called lc 2 formalism, which contains only the two physical degrees of freedom, allow for a subset of residual ...

Journal of High Energy Physics, 2019 We classify N =1 d = 4 kinematical and aristotelian Lie superalgebras with spa- tial isotropy, but not necessarily parity nor time-reversal invariance. Employing a quater- nionic formalism which makes rotational covariance manifest and simplifies many of

Journal of High Energy Physics, 2023 The asymptotic symmetries of electromagnetism in all higher spacetime dimensions d > 4 are extended, by incorporating consistently angle-dependent u(1) gauge transformations with a linear growth in the radial coordinate at spatial infinity. Finiteness of

International Journal of Modern Physics D, 2016 The equations of Hamiltonian gravity are often considered ugly cousins of the elegant and manifestly covariant versions found in the Lagrangian theory. However, both formulations are fundamental in their own rights because they make different statements about the nature of spacetime and its symmetries.

Asymptotic symmetries of Yang-Mills fields in Hamiltonian formulation
Journal of High Energy Physics, 2020 We investigate the asymptotic symmetry group of the free SU(N )-Yang-Mills theory using the Hamiltonian formalism. We closely follow the strategy of Henneaux and Troessaert who successfully applied the Hamiltonian formalism to the case of gravity and ...

Hamiltonian structure and asymptotic symmetries of the Einstein-Maxwell system at spatial infinity
Journal of High Energy Physics, 2018 We present a new set of asymptotic conditions for gravity at spatial infinity that includes gravitational magnetic-type solutions, allows for a non-trivial Hamiltonian action of the complete BM S 4 algebra, and leads to a non-divergent behaviour of the ...

On free Lie algebras and particles in electro-magnetic fields
Journal of High Energy Physics, 2017 The Poincaré algebra can be extended (non-centrally) to the Maxwell algebra and beyond. These extensions are relevant for describing particle dynamics in electromagnetic backgrounds and possibly including the backreaction due the presence of multipoles ...

Gauss’ Law and string-localized quantum field theory
Journal of High Energy Physics, 2020 The quantum Gauss Law as an interacting field equation is a prominent feature of QED with eminent impact on its algebraic and superselection structure. It forces charged particles to be accompanied by “photon clouds” that cannot be realized in the Fock ...

COLORED SYMMETRIES IN SPACE–TIME
Computers & Mathematics with Applications, 1986 AbstractThe paper displays a single objective: to show the emergence of symmetries as a universal, archetypal, self-organizing phenomenon which originates in an infinite number of forms all having the same trihedral innate structure. These forms have been generated by the use of a single-type, right-handed element containing three spatial dimensions ...

Symmetries in planning problems [PDF]
, 2003 Symmetries arise in planning in a variety of ways. This paper describes the ways that symmetry aises most naturally in planning problems and reviews the approaches that have been applied to exploitation of symmetry in order to reduce search for plans. It
