Holographic Dark Energy in LRS Bianchi Type-II Space Time

Abstract

In the present paper, we have discussed holographic dark energy in LRS Bianchi type-II space time. The Einstein’s field equation are solved by using two assumption. One of them is law off variation for the Hubble parameter, which gives a constant value of deceleration parameter and another is a relation between two metric co-efficient. The law of variation generates power law and exponential form of average scale factor in terms of cosmic time. The physical and kinematical properties of the model are also discussed. The holographic dark energy (DE) EOS parameter behaves like constant,i,e 1     ,which is mathematically equivalent to cosmological constant  for 0  n ,whereas the holographic dark energy EOS parameter behaves like quintessence for 0  n .
