Özet:

 


 
                         Various approaches are developed that provide a 
unification of the early inflationary epoch of the universe and dark energy 
(cosmic accelerating expansion case). In one respect, we express this 
unification in a universal thermodynamic framework within the context of 
F(T,TG) F   (   T  ,   T   G     )   F(T,TG)F(T,TG)F\left( T,T_{G} \right) gravity, where T T  TTT represents the torsion 
invariant and TG  T   G    TGTGT_{G} is the teleparallel equivalent of the Gauss--Bonnet 
term. For a Friedmann-Robertson-Walker universe model bounded by the 
dynamical apparent horizon, we explore the generalized second law of 
gravitational thermodynamics (GSLT). Finally, we discuss the super inflation 
mechanism, the deceleration case (radiation and dust regions), and the late 
time cosmic acceleration of the universe into the validity of the GSLT that 
we obtain.
