We develop the n-dimensional cosmology for gravity, where
is the Gauss–Bonnet topological invariant. Specifically, by the so-called Noether Symmetry Approach, we select
power-law models where k is a real number. In particular, the case
for
results equivalent to General Relativity showing that we do not need to impose the action
to reproduce the Einstein theory. As a further result, de Sitter solutions are recovered in the case where
is non-minimally coupled to a scalar field. This means that issues like inflation and dark energy can be addressed in this framework. Finally, we develop the Hamiltonian formalism for the related minisuperspace and discuss the quantum cosmology for this model.
