| dc.description.abstractEn | We investigate the propagation of the scalar waves in the FLRW universes beginning with a Big Bang and ending with a Big Crunch, a Big Rip, a Big Brake, or a Sudden Singularity. We obtain the sharp description of the asymptotics for the solutions of the linear Klein–Gordon equation, and similar results for the semilinear equation with a subcritical exponent. We prove that the number of cosmological particle creation is finite under general assumptions on the initial Big Bang and the final Big Crunch or Big Brake. | |
