摘要
We discuss cosmological models in six-dimensional spacetime. For codimension-1 branes, we consider a (4+1) braneworld model and discuss its cosmological evolution. For codimension-2 branes, we consider an infinitely thin conical braneword model in the presence of an induced gravity term on the brane and a Gauss-Bonnet term in the bulk. We discuss the cosmological evolution of isotropic and anisotropic matter on the brane. We also briefly discuss cosmological models in six-dimensional supergravity.
