Blowup of the Nonlinear Klein-Gordon Equation in FLRW Spacetimes

Gregory Mwamba
Graduate Student
University of California – Merced

The nonlinear Klein-Gordon equations are a class of important evolution equations that describe the movement of spinless relativistic particles, which can lend understanding in many physical applications. In this talk we will demonstrate a sufficient condition for blowup of the nonlinear Klein-Gordon equation, with arbitrarily positive initial energy in Friedmann-Lemaître-Robertson-Walker spacetimes. This is accomplished using an established concavity method that has been employed for similar PDEs in Minkowski space. This proof relies on the energy inequality associated with this equation.

This talk will be online at the following zoom link: https://wisconsin-edu.zoom.us/j/94983351854 and will also be streamed in EMS E495.
