Einstein Equations from Riemann-only Gravitational Actions
Durmus Demir, Oktay Dogangun, Tonguc Rador +1
Here show that, pure affine actions based solely on the Riemann curvature tensor lead to Einstein field equations for gravitation. The matter and radiation involved are general eno…
Extra Dimensions, Dilaton and Dark Energy
Tonguç Rador
In view of the recent observations showing that the universe is accelerating we discuss dilaton and radion stabilization from a phenomenological perspective using perfect fluid sou…
Acceleration of the Universe via f(R) Gravities and The Stability of Extra Dimensions
Tonguç Rador
We discuss the possibility of obtaining the present acceleration of the universe via f(R) gravity theories which recently attracted much attention. It is known that f(R) theories g…
T and S dualities and The cosmological evolution of the dilaton and the scale factors
Tonguç Rador
Cosmologically stabilizing radion along with the dilaton is one of the major concerns of low energy string theory. One can hope that T and S dualities can provide a plausible answe…
Stabilization of Extra Dimensions and The Dimensionality of the Observed Space
Tonguç Rador
We present a simple model for the late time stabilization of extra dimensions. The basic idea is that brane solutions wrapped around extra dimensions, which is allowed by string th…
Intersection Democracy for Winding Branes and Stabilization of Extra Dimensions
Tonguç Rador
We show that, in the context of pure Einstein gravity, a democratic principle for intersection possibilities of branes winding around extra dimensions in a given partitioning yield…
