Abstract
Primordial gravitational waves are created during the de Sitter phase of an exponentially, expanding (inflationary) universe, due to quantum zero-point vacuum fluctuations. These waves produce fluctuations in the temperature of the cosmic background radiation (CBR). We calculate the multipole moments of the correlation function for these temperature fluctuations in a spatially closed Friedmann-Robertson-Walker (FRW) cosmological model. The results are compared to the corresponding multipoles in the spatially flat case. The differences are small unless the density parameter today, , is greater than 2.
