| dc.description | The existence of a fundamental length (or fundamental time) has been conjecture in many contexts. Here one discusses some consequences of a fundamental constant of this type, which emerges as a consequence of deformation-stability considerations leading to a non-commutative space-time structure. This mathematically well defined structure is sufficiently constrained to allow for unambiguous experimental predictions. In particular one discusses the phase-space volume modifications and their relevance for the calculation of the GZK sphere. Corrections to the spectrum of the Coulomb problemb are also computed. | |
