Quantum symmetry, the cosmological constant and Planck-scale phenomenology
We present a simple algebraic mechanism for the emergence of deformations of Poincaré symmetries in the low-energy limit of quantum theories of gravity. The deformations, called κ-Poincaré algebras, are parametrized by a dimensional parameter proportional to the Planck mass, and imply modified energy–momentum relations of a type that may be …
