Abstract
Present work is a study of a particular two brane model in 5-dim, in which a primordial scalar field (living in the hidden brane) reproduces inflation effects for very early times. By using a novel ansatz, we obtain a set of solutions that are topological dependent and establish restrictions over the evolution in each brane. An important aspect to consider is the scale of compactification, $$R$$ in the evolution equations, therefore two limits are studied: first when $$R$$ is negligible, and later with the $$R$$ contribution playing an important roll in the adjusted parameters to obtain $$N_0\approx 70$$ e-foldings. As a result of having inflationary solutions in the hidden brane, similar behavior is reflected in our brane due to the constraint equations.
