ACCELERATING BIANCHI TYPE-VI0 BULK VISCOUS COSMOLOGICAL MODELS IN LYRA GEOMETRY

Abstract

 The present study deals with spatially homogeneous and totally anisotropic Bianchi type-VI0 bulk viscous cosmological models in LYRA GEOMETRY. The Einstein’s field equations have been solved exactly by taking the shear (s) in the model proportional to expansion scalar (q) which leads to A=Bn, where A and B are metric functions and n is a positive constant (n>1). We also adopt a condition xq=L (constant) where x is the coefficient of BULK VISCOSITY. It has been found that the displacement vector (b) is a decreasing function of time and it approaches to a small positive value at late time which is supported by recent observations. It is also found that the distance modulus curve of derived model matches with observations perfectly.
