Electromagnetic Mass in Dimensional Space-times
Saibal Ray
Einstein-Maxwell field equations correspoding to higher dimensional description of static spherically symmetric space-time have been solved under two specific set of conditions, vi…
The Dynamic Cosmological Term : Some Aspects of Phenomenological Models
Utpal Mukhopadhyay, Saibal Ray
Choosing a phenomenological model of , viz. , it has been shown that this model of is equivalent to other three types of , , $Λ\sim \ddo…
Dark energy with polytropic equation of state
Utpal Mukhopadhyay, Saibal Ray
Equation of state parameter plays a significant role for guessing the real nature of dark energy. In the present paper polytropic equation of state is chosen for some of t…
Dark energy models with time-dependent gravitational constant
Saibal Ray, Utpal Mukhopadhyay
Two phenomenological models of , viz. and are studied under the assumption that is a time-variable parameter. Both models show that $G…
Scenario of Accelerating Universe from the Phenomenological Λ- Models
Saibal Ray, Utpal Mukhopadhyay, Farook Rahaman +1
Dark matter, the major component of the matter content of the Universe, played a significant role at early stages during structure formation. But at present the Universe is dark en…
