Brief Description:
Special Note: Please note the room change

The role of deformations in physics and mathematics lead to the deformation philosophy promoted in mathematical physics by Flato since the 70's, exemplified by deformation quantization and its manifold avatars, including quantum groups and the ``dual" aspect of quantum spaces. Deforming Minkowski space-time and its symmetry to anti de Sitter has significant physical consequences that we sketch (e.g. singleton physics). We end by presenting an ongoing program in which anti de Sitter would be quantized in some regions, speculating that this might explain baryogenesis in a universe in accelerated expansion.
