On κ-deformation and triangular quasibialgebra structure
We show that, up to terms of order κ−5, the κ-deformed Poincaré algebra can be endowed with a triangular quasibialgebra structure. The universal R matrix and coassociator are given explicitly to the first few orders. In the context of κ-deformed quantum field theory, we argue that this structure, assuming it exists to all orders, ensures that states of any number of identical particles, in any ...
متن کاملAbsorption of TeV Photons and κ-Deformation of Relativistic Symmetries
It is shown how the increase of classical threshold for hard photon absorption on far infrared background can be achieved with the use of deformed kinematics, described by κ-deformation of Poincaré symmetries in bicrossproduct basis. We consider the dependence of absorption threshold on the scattering angles for ingoing photons as well as outgoing e − e pair. We discuss in detail the threshold ...
متن کاملκ-Minkowski spacetime as the result of Jordanian twist deformation
Two one-parameter families of twists providing κ−Minkowski ∗−product deformed spacetime are considered: Abelian and Jordanian. We compare the derivation of quantum Minkowski space from two perspectives. First one is the Hopf module algebra point of view, which is strictly related with Drinfeld’s twisting tensor technique. An other one relies on an appropriate extension of deformed realizations ...
متن کاملSMALL u κ AND LARGE 2 κ FOR SUPERCOMPACT κ
Garti and Shelah [2] state that one can force uκ to be κ+ for supercompact κ with 2κ arbitrarily large, using the technique of Džamonja and Shelah [1]. Here we spell out how this can be done. §
متن کاملon semihypergroups and hypergroups
in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...
