Abstract: | Taking the cosmological expansion rate directly as a function of field φ, H=H(φ), we present a new exact solution to Einstein's equations that describe the evolution of cosmological chaotic inflation model. The inflation is driven by the evolution of scalar field with inflation potential V(φ)=(λ/8)(φ2-υ2)2. The spectral indices of the scalar density ns and gravitational wave fluctuations ng are computed.The value of ns lies well inside the limits set by the cosmicbackground explorer satellite. |
