چکیده
A bstract Asymptotic symmetries in Carrollian gravitational theories 3+1 space and time dimensions obtained from “magnetic” “electric” ultrarelativistic contractions of General Relativity are analyzed. In both cases, parity conditions needed to guarantee a finite symplectic term, analogy with Einstein gravity. For the magnetic contraction, when Regge-Teitelboim imposed, asymptotic described by Carroll group. With Henneaux-Troessaert conditions, symmetry algebra corresponds BMS-like extension algebra. electric because lapse function does not appear boundary term ensure well-defined action principle, is truncated, for semidirect sum spatial rotations translations. Similarly, given an infinite number odd supertranslations. Thus, point view symmetries, contraction can be seen as smooth limit Relativity, contrast its counterpart.

Asymptotic symmetries in 3d gravity with torsion
Three-dimensional (3d) gravity has been used as a theoretical laboratory to test some of the conceptual problems of quantum gravity. The phase space structure of 3d gravity is known to be of great importance not only at the classical level, but also for a clear understanding of the related quantum structure [1,2]. In particular, the Virasoro algebra of the asymptotic symmetry plays a central ro...
متن کاملGravity cutoff in theories with large discrete symmetries.
We set an upper bound on the gravitational cutoff in theories with exact quantum numbers of large N periodicity, such as Z(N) discrete symmetries. The bound stems from black hole physics. It is similar to the bound appearing in theories with N particle species, though a priori, a large discrete symmetry does not imply a large number of species. Thus, there emerges a potentially wide class of ne...
متن کاملAsymptotic Symmetries in General Relativity
The symmetries of flat Minkowski space-time are well known to be described by the Poincare group, and include translations and rotations. On the other hand, the symmetries of an asymptotically flat space-time are described by the infinite-dimensional BondiMatzner-Sachs (BMS) group. This group includes new types of transformations called supertranslations and superrotations, whose physical inter...
متن کاملGravity and global symmetries.
There exists a widely spread notion that gravitational effects can strongly violate global symmetries. If this is correct, it may lead to many important consequences. We will argue, in particular, that nonperturbative gravitational effects in the axion theory lead to a strong violation of CP invariance unless they are suppressed by an extremely small factor g <∼ 10−82. One could hope that this ...
متن کاملDynamical symmetries in noncommutative theories
In the present work we study dynamical space-time symmetries in noncommutative relativistic theories by using the minimal canonical extension of the Doplicher, Fredenhagen and Roberts algebra. Our formalism is constructed in an extended space-time with independent degrees of freedom associated with the object of noncommutativity θ . In this framework we consider theories that are invariant unde...
