abstract

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

    A κ-deformed star product modifies the inflationary perturbation equation, yielding a (ln k)^2 correction to the power spectrum and a claimed ACT DR6 bound on the deformation length.
