Signature Change by GUP
T. Ghaneh, F. Darabi, H. Motavalli
We revisit the issue of continuous signature transition from Euclidean to Lorentzian metrics in a cosmological model described by FRW metric minimally coupled with a self interacti…
Multi-Dimensional Cosmology and DSR-GUP
K. Zeynali, F. Darabi, H. Motavalli
A multidimensional cosmology with FRW type metric having 4-dimensional space-time and -dimensional Ricci-flat internal space is considered with a higher dimensional cosmological…
Eguchi-Hanson like space-times in F(R) gravity
S. H. Hendi, R. B. Mann, N. Riazi +1
We consider a model of gravity in which exponential and power corrections to Einstein- gravity are included. We show that this model has 4-dimensional Eguchi-Hanson type…
Black hole thermodynamics and modified GUP consistent with doubly special relativity
K. Zeynali, F. Darabi, H. Motavalli
We study the black hole thermodynamics and obtain the correction terms for temperature, entropy, and heat capacity of the Schwarzschild black hole, resulting from the commutation r…
Multi-Dimensional Cosmology and GUP
K. Zeynali, F. Darabi, H. Motavalli
We consider a multidimensional cosmological model with FRW type metric having 4-dimensional space-time and -dimensional Ricci-flat internal space sectors with a higher dimension…
Signature Change in Noncommutative FRW Cosmology
Taymaz Ghaneh, Farhad Darabi, Hossein Motavalli
The conditions for which the no boundary proposal may have a classical realization of a continuous change of signature, are investigated for a cosmological model described by FRW m…
