Cosmology: Kaluza-Klein Theory

Scientific paper

The authors present a cosmological solution of an eight-dimensional Kaluza-Klein theory with Georgi's three-family SU(11) model in M4, to which a matter term is added. In this solution, the general behavior of the scale factors is depicted in four stages. In stage one, both R3 and R4 expand with time; in stage two, R4 is a constant while R3 is an inflationary solution and R3 will continue to increase with time monotonically while R4 recollapses toward its minimum in stage three; finally, in stage four, R4 will be stabilized at RKK through some quantum effects and R3 expands with time in the usual FRW way in which the four-dimensional cosmological constant becomes zero.
