Spherical Symmetric Solution in f(R) Model Around Charged Black Hole
A. Aghamohammadi, Kh. Saaidi, M. R. Abolhasani +1
A static, asymptotically flat, spherically symmetric solutions is investigated in f(R) theories of gravity for a charged black hole. We have studied the weak field limit of f(R) gr…

Standard Cosmological Evolution in f(R) Model to Kaluza Klein Cosmology
A. Aghmohammadi, Kh. Saaidi, M. R. Abolhassani +1
In this paper, using theory of gravity we explicitly calculate cosmological evolution in the presence of a perfect fluid source in four and five dimensional, space time in w…
