Future stability of solutions of the Einstein-nonlinear scalar field system with decelerated expansion
Louie Bernhardt
We study solutions to the Einstein equations coupled to a nonlinear scalar field with exponential potential. This system admits Friedmann-Lemaître-Robertson-Walker solutions under…
