Stable Cosmology from Minimal Theory of Mass-Varying Massive Gravity
Ahmad Khoirul Falah, Andy Octavian Latief, Husin Alatas +1
We study cosmological perturbations in the minimal theory of mass-varying massive gravity (MTMVMG), a constrained extension of mass-varying massive gravity that propagates only thr…
Some Cosmological Consequences of Higher Dimensional Klein-Gordon-Rastall Theory
Tegar Ari Widianto, Ahmad Khoirul Falah, Agus Suroso +2
Using dynamical system analysis, we investigate some cosmological consequences of Rastall gravity coupled to a scalar field (called the Klein-Gordon-Rastall theory) with exponentia…
Higher-Dimensional Minimal Theory of Mass-Varying Massive Gravity And Its Cosmological Consequences
Ahmad Khoirul Falah, Andy Octavian Latief, Husin Alatas +1
In this paper we construct higher-dimensional minimal theory of mass-varying massive gravity (MTMVMG) where the masslike scalar potential is coupled to a vielbein potential, unlike…
On the Lapse Function of FLRW Accelerated Expanding Universe in dRGT Massive Gravity Theory
Husin Alatas, Ahmad K. Falah, Trio Wibowo +2
In this report, we discuss the behavior of coordinate-time dependent lapse function of FLRW metric of an accelerated expanding universe in the de Rham-Gabadadze-Tolley massive grav…
