Аннотация
We present a cosmological model constructed using a pure geometric field theory. The unification principle implies defining any physical object in the model using the building blocks of the geometry used, the Absolute Parallelism (AP) geometry. The type of AP geometry used has simultaneously nonvanishing curvature and torsion. The AP geometric structure, used for this application, satisfies the cosmological principle and switches off the electromagnetic sector of the theory automatically. The model obtained is found to be free from particle horizons and flatness problems. This model can be considered as representing a transition phase between a decelerated and accelerated Universe. Conservation in the model is guaranteed by the theory used.
