| Abstract | Proposals that quantum gravity gives rise to non-commutative spacetime geometry and deformations of Poincaré symmetry are examined in the context of (2+1)dimensional quantum gravity. The results are expressed in five lessons, which summarise how the gravitational constant, Planck’s constant and the cosmological constant enter the non-commutative and non-cocommutative structures arising in (2+1)dimensional quantum gravity. It is emphasised that the much studied bicrossproduct κ-Poincaré algebra does not arise directly in (2+1)-dimensional quantum gravity Based on talk given at the conference “From Quantum to Emergent Gravity: Theory and Phenomenology” June 11-15 2007, Trieste, Italy |
