Abstract

We generalise the entropic force description of gravity into κ\kappa-Minkowski space-time and derive the κ\kappa-deformed corrections to the Newton's gravitational force. Using this we show the appearance of logarithmic correction as the first order κ\kappa-deformed correction term to Bekenstein-Hawking entropy. Further we also derive the κ\kappa-deformed Friedmann equations and study the evolution of scale factor in κ\kappa-deformed space-time. Finally we show that the κ\kappa-deformation parameter avoids the initial singularity in early universe by providing a bounce behaviour for the case of spatially flat and closed universe.
