- Phase Space Solutions in Scalar-Tensor Cosmological Models José C. C. de Souza Alberto Saa Física, Astronomía y Matemáticas An analysis of the solutions for the field equations of generalized scalar-tensor theories of gravitation isperformed through the study of the geometry of the phase space and the stability of the solutions, with specialinterest in the Brans-Dicke model. Particularly, we believe to be possible to find suitable forms of the Brans-Dicke parameter w and potential V of the scalar field, using the dynamical systems approach, in such a way thatthey can be fitted in the present observed scenario of the Universe. 2005 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46435704 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
