(2+1) dimensional cosmological models in f(R; T) gravity with (R; T)
Safiqul Islam, Praveen Kumar, G. S. Khadekar +1
We intend to study a new class of cosmological models in modified theories of gravity, hence define the cosmological constant as a function of the trace of the stress…
Filter theory of IL-algebras
Safiqul Islam, Arundhati Sanyal, Jayanta Sen
In this paper, we introduce the concept of filter on IL-algebra. It is proved that this concept generalizes the notion of filter on Residuated Lattices. Prime filters on IL-algebra…
Ideal on CL-algebra
Safiqul Islam
In this paper, we introduce the concept of ideal on CL-algebra. It is proved that this concept generalizes the notion of ideal on Residuated Lattices. Prime ideal on CL-algebra are…
Magnetic Field of a Compact Spherical Star under f(R,T) Gravity
Safiqul Islam, Shantanu Basu
We present the interior solutions of distributions of magnetised fluid inside a sphere in gravity. The magnetised sphere is embedded in an exterior Reissner-Nordström metr…
Charged wormholes supported by 2-fluid immiscible matter particles
Safiqul Islam, Md Arif Shaikh, Tapas Kumar Das +2
We provide a 2-fluid immiscible matter source that supplies fuel to construct wormhole spacetime. The exact wormhole solutions are found in the model having, besides real matter or…
A Reissner-Nordström black hole in the Friedman-Robertson-Walker universe
Safiqul Islam, Priti Mishra, Somi Aktar +1
A charged, non-rotating, spherically symmetric black hole which has cosmological constant (Reissner-Nordström+ or RN+), active gravitational mass and electric charge…
A parametric model to study the mass radius relationship of stars
Safiqul Islam, Satadal Datta, Tapas K Das
In static and spherically symmetric spacetime, we solve the Einstein Maxwell equations. The effective gravitational potential and the electric field for charged anisotropic fluid a…
The higher dimensional gravastars
Farook Rahaman, Subenoy Chakraborty, Saibal Ray +2
A new model of gravastar is obtained in -dimensional Einstein gravity. This class of solutions includes the gravastar as an alternative to D-dimensional versions of the Schwarzs…
Searching for higher dimensional wormholes with noncommutative geometry
Farook Rahaman, P. K. F. Kuhfittig, Saibal Ray +1
Noncommutative geometry, an offshoot of string theory, replaces point-like structures with smeared objects and has recently been extended to higher dimensions. The purpose of this…
The (2+1)-dimensional charged gravastars
Farook Rahaman, A. A. Usmani, Saibal Ray +1
This is a continuation and generalization of our earlier work on {\it gravastar} in (2+1) anti-de Sitter space-time to 2+1 dimensional solution of charged gravastar. Morphologicall…
Wormholes supported by two non-interacting fluids
Farook Rahaman, Saibal Ray, Safiqul Islam
We provide a new matter source that supplies fuel to construct wormhole spacetime. The exact wormhole solutions are found in the model having, besides real matter, an anisotropic d…
The (2+1)-dimensional gravastars
Farook Rahaman, Saibal Ray, A. A. Usmani +1
We propose a new model of a gravastar in (2+1) anti-de Sitter space-time. This new three dimensional configuration has three different regions with different equations of state: [I…
