Decrumpling or TVSD model explains why the universe is accelerating today
Forough Nasseri
Within the framework of a model universe with time variable space dimension (TVSD), known as decrumpling or TVSD model, we show the present value of the deceleration parameter is n…
Time variation of the gravitational coupling constant in decrumpling cosmology
Forough Nasseri
Within the framework of a model universe with time variable space dimension (TVSD) model, known as decrumpling or TVSD model, we study the time variation of the gravitational coupl…
Corrections to the Fine Structure Constant in the Spacetime of a Cosmic String from the Generalized Uncertainty Principle
Forough Nasseri
We calculate the corrections to the Fine Structure Constant in the spacetime of a cosmic string. These corrections stem from the generalized uncertainty principle. In the absence o…
Schwarzschild Black Hole in Noncommutative Spaces
Forough Nasseri
We study the effects of noncommutative spaces on the horizon, the area spectrum and Hawking temperature of a Schwarzschild black hole. The results show deviations from the usual ho…
The Event Horizon of The Schwarzschild Black Hole in Noncommutative Spaces
Forough Nasseri
The event horizon of Schwarzschild black hole is obtained in noncommutative spaces up to the second order of perturbative calculations. Because this type of black hole is non-rotat…
Time variation of the fine structure constant in decrumpling or TVSD model
Forough Nasseri
Within the framework of a model universe with time variable space dimension (TVSD), known as decrumpling or TVSD model, we study the time variation of the fine structure constant.…
