QUASI-DE SITTER SOLUTION IN \(F(T,(\nabla T)^2)\) TELEPARALLEL GRAVITY

Fedotov V.V., Chervon S.V.

This paper considers the relevance of the quasi-de Sitter solution for the modified \(F(T,(\nabla T)^2)\) teleparallel theory of gravity. The Hubble parameter is represented in the form: \(H = H_* + \epsilon e^{-Bt}\), where \(H_*, B - const\). The cosmological equations of the model with a perfect fluid are written for the following choice of function \(F: F = AT^n + \omega(T)\nabla_{\mu}T\nabla^{\mu}T\). The evolution of matter density perturbations in the absence of pressure perturbations is considered.
