Coupling of gravity to matter, spectral action and cosmic topology
Coupling of gravity spectral action cosmic topology
font style='font-size:12px;'>
2011/7/26
Abstract: We consider a model of modified gravity based on the spectral action functional, for a cosmic topology given by a spherical space form, and the associated slow-roll inflation scenario. We co...
