- Attractors in Dark Energy Models with Born-Infeld Scalar Field Ronaldo Carlotto Batista Luís Raul Weber Abramo Thiago dos Santos Pereira Física, Astronomía y Matemáticas We derive, in the large scale limit, analytical solutions for a dark energy model described by the Born-Infeldfield plus a perfect fluid, both for homogeneous background and first order perturbations. These analyticalresults are compared with numerical solutions in a model with radiation, pressureless matter and the field. Weinvestigate the non-adiabatic perturbed pressure associated with this attractor and whether it corresponds toisocurvature contribution. 2005 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46435705 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4B Vol.35
