Abstract
The full algebra of relativistic quantum mechanics (Lorentz plus Heisenberg ) is unstable. Stabilization by deformation leads to a new deformation para meter epsilonl(2), l being a length and epsilon a +/- sign, The implication s of the deformed algebras for the uncertainty principle and the density of states are worked out and compared with the results of past analysis follo wing from gravity and string theory.
