QUASI-DE SITTER SOLUTION IN F(T,(∇T)2) TELEPARALLEL GRAVITY
Fedotov V.V., Chervon S.V.
This paper considers the relevance of the quasi-de Sitter solution for the modified F(T,(∇T)2) teleparallel theory of gravity. The Hubble parameter is represented in the form: H=H∗+ϵe−Bt, where H∗,B−const. The cosmological equations of the model with a perfect fluid are written for the following choice of function F:F=ATn+ω(T)∇μT∇μT. The evolution of matter density perturbations in the absence of pressure perturbations is considered.
Keywords: Teleparallel gravity, quasi-de Sitter solution, cosmological perturbations.
