چکیده Here, we study the logamediate inflation in the context of f(T) teleparallel gravity. f(T)-gravity is a generalization of the teleparallel gravity which is formulated on the Weitzenbock spacetime, characterized by the vanishing curvature tensor (absolute parallism) and the non-vanishing torsion tensor. We consider a f(T)-gravity model which is sourced by a canonical scalar field. Assuming a power-law f(T) function in the action, we investigate an inflationary universe with the logamediate scale factor. Our results show that although the logamediate inflation is completely ruled out by the observational data in the standard inflationary scenario based on the Einstein gravity, it can be compatible with the 68\% CL joint region of Planck 2015 TT,TE,EE+lowP data in the framework of f(T)-gravity.
