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