Remarks on doubly special relativity theories and gravity
Original language description
Modifications of special relativity by the introduction of an invariant energy and/or momentum level (doubly special relativity, DSR) or by an energy-momentum dependence of the Planck constant (generalized uncertainty principle, GUP) are compared with classical gravitational effects in an interaction process. For the low-energy limit of the usual formulations of DSR to be equivalent to Newtonian gravity a restrictive condition is found. GUP yields an effective repulsion.

Poznamky o dvakrat specialne teorie relativity a gravite
Czech description
Modifikace specialni teorie relativity zavedenim invariantni energie a/nebo impulzu (dvakrat specialni relativira, DSR) nebo zavislosti Planckovy konstanty na energie-impulzu (zobecneny princip neurcitosti, GUP) jsou porovnavane s klasickou gravitaci v interakcnim procesu. Restriktivni podminka, aby nizkoenergeticka limita DSR byla ekvivalentni s Newtonovkou gravitaci, byla nalezena. GUP vede k efektivnimu odpuzeni.
