Let G be a real reductive Lie group and let τ : G −→ GL(V ) be a real reductive representation of G with (restricted) moment map mg : V {0} −→ g. In this work, we introduce the notion of nice space of a real reductive ...

Orbits in the principal planes of triaxial potentials are known to be prone to unstable motion normal to those planes, so that three dimensional investigations of those orbits are needed even though they are two dimensional. ...

We created a triaxial stellar system through the cold dissipationless collapse of 100,000 particles whose evolution was followed with a multipolar code. Once an equilibrium system had been obtained, the multipolar expansion ...

Landscape unit discrimination for pedological surveys by orbital spectral response. The objective of tins study was compare two soil survey methods. The first was performed by methods traditionally used to distinguish ...

In several previous papers we had investigated the orbits of the stars that make up galactic satellites, finding that many of them were chaotic. Most of the models studied in those works were not self-consistent, the single ...

We retrospectively studied the computed tomography scans of the orbit in 75 patients in order to identify the presence of incidental calcifications (scleral and trochlear apparatus calcifications). These imaging findings ...

O objetivo deste trabalho foi comparar dois métodos de levantamentos de solos. O primeiro foi realizado por meio de metodologias tradicionalmente utilizadas na distinção das unidades de paisagem e discriminação das classes ...
