The minimum masses of black holes from the generalized uncertainty principle and the uncertainty principle

In this paper we compare the minimum masses of Schwarzschild black hole obtained from the generalized uncertainty principle and the Heisenberg uncertainty principle. Three minimum masses are obtained. The first two are the order of Planck mass which can be normally accepted. The last one based on Scardigli’s hypothesis and consideration is about M _c ?10¹⁵ g～10²⁰ M _pl which may be problematic. Whether right or wrong, it needs the astronomical observations.
