Abstract
The pair production rates for spin-0 and particles are calculated on spaces of the form , with corresponding to (flat); (flat, compactified); (positive curvature); and (negative curvature), with and without a background magnetic field on . The motivation is to elucidate the effects of the curvature and background magnetic field. Contrasting effects for positive and negative curvature on the two cases of spin are obtained. For positive curvature, we find enhancement for spin-0 and suppression for , with the opposite effect for negative curvature.
