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 --dimensional FLRW spacetimes (). In conformal time the field satisfies a dampe…

Classical Solutions of Higher Dimensional Einstein-Maxwell-Higgs System With Nontrivial Potential: Global Existence and Completeness
Mirda Prisma Wijayanto, Fiki Taufik Akbar, Bobby Eka Gunara
We study the Cauchy problem of higher dimensional Einstein-Maxwell-Higgs system in the framework of Bondi coordinates. As a first step, the problem is reduced to a single first-ord…
