Spherical symmetric black hole based on Higher derivative gravity

Abstract

The theory of higher derivative gravity is proposed to solve the non-renormalizable problem in quantum gravity.In this article, We use two numerical methods to fit another static spherically symmetric black hole besides the Schwarzschild black hole.We obtain approximate expressions for two numerical solutions, both of which contain a parameter that deviates from the Schwarzschild degree.We also analyze their degree of precision and the quasi-normal modes of the black hole.
