1. Quantum baker maps for spiraling chaotic motion
We define a coupling of two baker maps through a pi/2 rotation both in position and in momentum. The classical trajectories thus exhibit spiraling, or loxodromic motion, which is only possible for conservative maps of at least two degrees of freedom. This loxodromic baker map is still hyperbolic, that is, fully chaotic. Quantization of this map follows on si

2. O Teorama da Convexidade do Mapa do Momento
In this dissertation we presented the Atiyah-Guillemin-Sternberg convexity theorem about the image of the moment map in the case of Hamiltonian torus action on compact connected symplectic manifold. This result gives, in certain sense, a generalization to Schur theorem about relationship between eigenvalues and diagonal entries of Hermitian matrix. With this

3. Estudo numerico de um escoamento bifasico, laminar : padrões anular e estratificado
A numerical solution of the two-dimensional momentum equations for a two-phase, Newtonian fluid(s), steady, laminar, axial, fully developed flow in a long, horizontal, circular pipe is conducted. The annular and stratified patterns are considered by assuming the interface between the phases to be either circular-cylindrical or an arc-segment of a cylindrical
