- On the Non-integrability of a Class of Hamiltonian Cosmological Models L. A. A. Coelho J. E. F. Skea T. J. Stuchi Física, Astronomía y Matemáticas The method of Morales and Ramis determines whether a given Hamiltonian system is non-integrable. Weapply this method to Friedmann Robertson Walker models with a self-interacting scalar field and cosmologicalconstant. It is shown that, with the exception of a set of measure zero, these models are non-integrable. Ourresults complement those of Helmi and Vucetich who used the Painlev´e property to find integrable modelswithin this class. 2005 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46435707 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
