Generalized Chaplygin gas model, supernovae, and cosmic topology
Generalized Chaplygin gas model, supernovae, and cosmic topology
In this work we study to which extent the knowledge of spatial topology may place constraints on the parameters of the generalized Chaplygin gas (GCG) model for unification of dark energy and dark matter. By using both the Poincaré dodecahedral and binary octahedral spaces as the observable spatial topologies, we …
