【 摘 要 】

We have studied five-dimensional homogeneous cosmological models with variable 𝐺 and bulk viscosity in Lyra geometry. Exact solutions for the field equations have been obtained and physical properties of the models are discussed. It has been observed that the results of new models are well within the observational limit.
