Abstract

The C-field cosmological model based on the Hoyle--Narlikar theory with variable gravitational constant G is investigated. To obtain the deterministic value of C=dC/dt we present certain constant values for integration constants. The creation field is proportional to time. G and ρ (density) decrease with time and the universe represents an expanding universe. The creation field increases as time increases. We find C=√{1/(2πf)}t where
f>0. Thus C=1 when f=1/(2π)>0.
