Global existence of solutions for semilinear wave equations in Friedmann-Lema\itre-Robertson-Walker spacetime
Abstract
We consider the nonlinear massless wave equation belonging to some family of the Friedmann-Lema\itre-Robertson-Walker (FLRW) spacetime. We prove the global in time small data solutions for supercritical powers in the case of decelerating expansion universe.
