Аннотация:Contribution to: International Conference on Quantum Field Theory, High-Energy Physics, and CosmologyIn this paper, inflation is considered in the scalar tensor theory with a nonlinear kinetic term. It was shown that in the case of a power law potential (V(ϕ)=V_0 ϕ^α) and κ>0 the theory cannot describe the current observational data. In the case of κ<0, the description of the theory becomes more complicated, since the slow roll approximation does not work in this case. For this case with potentials V(ϕ)=0 and V(ϕ)=V_0|ϕ|^1.5, the possibility of obtaining inflation of more than 60 e-folds was considered.
