oai:localhost:PNK-18862022-08-17T05:54:44Z No-go theorem for inflation in Ricci-inverse gravity Tuan Q. Do Q1 In this paper, we study the so-called Ricci-inverse gravity, which is a very novel type of fourth-order gravity proposed recently. In particular, we are able to figure out both isotropically and anisotropically inflating universes to this model. More interestingly, these solutions are shown to be free from a singularity problem. However, stability analysis based on the dynamical system method shows that both isotropic and anisotropic inflation of this model turn out to be unstable against field perturbations. This result implies a no-go theorem for both isotropic and anisotropic inflation in the Ricci-inverse gravity. 2021-06-21T02:47:52Z 2021-06-21T02:47:52Z 2021 Article Working Paper https://link.springer.com/article/10.1140%2Fepjc%2Fs10052-021-09223-4 https://dlib.phenikaa-uni.edu.vn/handle/PNK/1886 10.1140/epjc/s10052-021-09223-4 en application/pdf The European Physical Journal C |
