A Sufficient Condition for Blowup of the Nonlinear Klein-Gordon Equation with Positive Initial Energy in FLRW Spacetimes
Jonathon McCollum, Gregory Mwamba, Jesús Oliver
In this paper we demonstrate a sufficient condition for blowup of the nonlinear Klein-Gordon equation with arbitrarily positive initial energy in Friedmann-Lemaître-Robertson-Walke…

Boundedness of the conformal hyperboloidal energy for a wave-Klein-Gordon model
Philippe G. LeFloch, Jesús Oliver, Yoshio Tsutsumi
We consider the global evolution problem for a model which couples together a nonlinear wave equation and a nonlinear Klein-Gordon equation, and was independently introduced by LeF…
