Query: Supernovae Constraints on DGP Model and Cosmic Topology   We study the constraints that the detection of a non-trivial spatial topology
may place on the parameters of braneworld models by considering the
Dvali-Gabadadze-Porrati (DGP) and the globally homogeneous Poincar\'e
dodecahedral spatial (PDS) topology as a circles-in-the-sky observable
topology. To this end we reanalyze the type Ia supernovae constraints on the
parameters of the DGP model and show that PDS topology gives rise to strong and
complementary constraints on the parameters of the DGP model.
