Özet

In order to solve the mystery of the accelerating and expanding universe model first, various dark energy candidates, such as Quintessence, Tachyon, k-essence, Phantom and DBI-essence, were investigated in detail in the f(Q) modified symmetric teleparallel gravitation theory for homogeneous and isotropic FRLW universe model. The f(Q)=aQn+b model is used to obtain solutions in f(Q) theory. Also, the physical behaviors of some cosmological parameters such as pressure and density were studied. Dark energy candidates were analyzed for different values of n with various graphs.
