Opis

The present book contains a short review on the historical development of cosmological models with variable gravitational and cosmological constant. Also, it contains some anisotropic models considering a time varying nature of these two so called constants. The authors have obtained two accelerating anisotropic models assuming a decaying energy density and discussed the time variation nature of the cosmological and gravitational constant.
