GUP corrected entropy of the Schwarzschild black hole in massive gravity.

Considering corrections to all orders in the Planck length on the density of quantum states from a generalized uncertainty principle (GUP), we calculate the statistical entropy of a scalar field on the background of the Schwarzschild black hole in massive gravity. As a result, we newly obtain the generalized Bekenstein-Hawking entropy depending on a gravitational mass without any artificial cutoff.
