Open and Closed World Models in Kaluza-Klein-Theory with Variables G and Λ
© 2014, Springer Science+Business Media New York. The field equation of higher dimensions theory, have been applied in the area of cosmology. The resulting differential equations are solved for open and closed. We derive a relation between the Einstein constant G(t) and the cosmological constant Λ(t) from the conservation law Tμ ν ;ν=0. We give a specific form of Λ(t) to solve the non-linear differential equations. Some cosmological parameters are calculated and some relevant cosmological problems are discussed.
