Four classes of modified relativistic symmetry transformations
J. Lukierski, A. Nowicki
We discuss the nonlinear transformations of standard Poincaré symmetry in the context of recently introduced Doubly Special Relativity (DSR) theories. We introduce four classes of…
Nonlinear and Quantum Origin of Doubly Infinite Family of Modified Addition Laws for Fourmomenta
J. Lukierski, A. Nowicki
We show that infinite variety of Poincaré bialgebras with nontrivial classical r-matrices generate nonsymmetric nonlinear composition laws for the fourmomenta. We also present the…
Doubly Special Relativity versus -deformation of relativistic kinematics
J. Lukierski, A. Nowicki
We argue that recently proposed by Amelino-Camelia et all [1,2] so-called doubly special relativity (DSR), with deformed boost transformations identical with the formulae for -d…
Absorption of TeV Photons and -deformed Poincaré algebra
G. Amelino-Camelia, J. Lukierski, A. Nowicki
We consider the process of collision between a hard photon and a soft photon producing an electron-positron pair, under the assumption that the kinematics be described according to…
kappa-Deformed Covariant Phase Space and Quantum-Gravity Uncertainty Relations
Giovanni Amelino-Camelia, Jerzy Lukierski, Anatol Nowicki
We describe the deformed covariant phase space corresponding to the so-called kappa-deformation of D=4 relativistic symmetries, with quantum ``time'' coordinate and Heisenberg alge…
Twisted Classical Poincaré Algebras
Jerzy Lukierski, Henri Ruegg, Valerij N. Tolstoy +1
We consider the twisting of Hopf structure for classical enveloping algebra , where is the inhomogenous rotations algebra, with explicite formulae given for $…
