Friedmann Robertson Walker models with Conformally Coupled Massive Scalar Fields are Non-integrable
L. A. A. Coelho, J. E. F. Skea, T. J. Stuchi
In this work we use a recently developed nonintegrability theorem of Morales and Ramis to prove that the Friedmann Robertson Walker cosmological model with a conformally coupled ma…

Chaos in a closed Friedmann-Robertson-Walker universe: An imaginary approach
S. E. Jorás, T. J. Stuchi
In this work we study the existence of mechanisms of transition to global chaos in a closed Friedmann-Robertson-Walker universe with a massive conformally coupled scalar field. We…

Chaotic exit to inflation: the dynamics of pre-inflationary universes
H. P. de Oliveira, I. Damiao Soares, T. J. Stuchi
We show that anisotropic Bianchi type-IX models, with matter and cosmological constant have chaotic dynamics, connected to the presence of a saddle-center in phase space. The topol…
