Description
The cosmological term is assumed to be a function of time such as <math>\Lambda =Ba^{-2}</math> where <math>a(t)</math> means the scale factor of standard cosmology. Analytical solutions for radiation dominated epoch and open universe are found. For closed universe, <math>k=+1</math>, and for flat universe, <math>k=0</math>, we show a numerical solution. In general the scenario of Big Bang is preserved in our case for the Friedmann-Robertson-Walker cosmology.
