Semilinear Klein-Gordon equation in space-time of black hole, which is gaining mass in the universe with accelerating expansion

Abstract

In this paper, we consider the propagation of waves in the space-time of a single black hole with a static Schwarzschild radius in the expanding universe, namely, the solutions of the linear and semilinear Klein-Gordon equations.
