Cosmological Stability of Massive Bigravity, is given a small mass. In particular, by specialising to the dRGT interaction potentials (.) we ensure that the notorious Boulware-Deser ghost mode is absent, and by allowing both metrics to be dynamical and taking the graviton mass to be of the order of the present-day Hubble rate, we can obtain 作者: organism 時間: 2025-3-22 05:03

Moreover, as demonstrated in Chap.?., cosmological background viability and linear stability rule out all but a small handful of the parameter space of the singly-coupled theory. By extending the matter coupling, we may be able to open up the space of observationally-allowed bimetric theories.作者: 背信 時間: 2025-3-24 06:52
