Corrosion is a global problem, which implies costs in industrialized countries of up to
4.5% of GDP, with either economic, but also social and environmental impacts. In the
case of Brazil, the waste of water supply ...

The expansion of Internet of Things (IoT) applications in large territories, such as Brazil,
faces significant connectivity challenges in remote areas with limited infrastructure and
urban environments with high interference. ...

This work investigates the stability, in the sense of the Morse index, of symmetric
central configurations in the N-body problem with interaction given by a general homogeneous
potential. By exploiting the symmetric ...

The main object of study in this work is partially hyperbolic diffeomorphisms. Fundamental
properties of these systems will be addressed, such as foliations, lifts, and linearization.
In addition, we discuss how a partially ...

The main object of study in this work is the absolute continuity property of invariant
foliations for dynamical systems. We begin by presenting the dynamical construction
of a classical example of a foliation that does ...
