Redshift Suppression of Nonlinear Scalar Fields in Accelerating FLRW Spacetimes

Mirda Prisma Wijayanto, Emir Syahreza Fadhilla, Ryan Sugihakim +3

We study small--data solutions of a nonlinear scalar field equation on spatially flat $d$--dimensional FLRW spacetimes ($d\ge 4$). In conformal time $\tau$ the field satisfies a damped…
