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

Karen Yagdjian, Anahit Galstian

Published 2024-04-13Version 1

In this paper, we prove the existence of global in-time small-data solutions of semilinear Klein-Gordon equations in space-time with a static Schwarzschild radius and variable mass in the expanding universe.
