    In this work, we have considered the power-law correction of entropy on the horizon. If the flat FRW Universe is filled with the n components fluid with interactions, the GSL of thermodynamics for apparent and event ...
  • Kazuharu Bamba; Ujjal Debnath; Kuralay Yesmakhanova; Petr Tsyba; Gulgasyl Nugmanova; Ratbay Myrzakulov (2013-04-19)
    We demonstrate two periodic or quasi-periodic generalizations of the Chaplygin gas (CG) type models to explain the origins of dark energy as well as dark matter by using the Weierstrass }(t), (t) and (t) functions ...

  • Shuvendu Chakraborty; Ujjal Debnath; Mubasher Jamil; Ratbay Myrzakulov 4, 5 (2012-12-28)
    In this work, we have calculated the deceleration parameter, statefinder parameters and EoS pa-rameters for different dark energy models with variable G correction in homogeneous, isotropic and non-flat universe for ...

  • Tanwi Bandyopadhyay; Ujjal Debnath; Mubasher Jamil; Faiz-ur-Rahman; Ratbay Myrzakulov (2013-04-19)
    In this work, we study the generalized second law of thermodynamics (GSL) at the apparent horizon of an evolving Lorentzian wormhole. We obtain the expressions of thermal variables at the apparent horizon. Choosing the ...
