In this work we investigate the relation between the fundamental group of a complete Riemannian manifold M and the quotient between the Weyl group and reflection group of a polar action on M, as well as the relation between ...

A singular Riemannian foliation F on a complete Riemannian manifold M is called a polar foliation if, for each regular point p, there is an immersed submanifold Sigma, called section, that passes through p and that meets ...

It is shown that ion-beam plasma electromagnetic right-hand polarized instabilities can be stabilized by nonlinear left-hand polarized waves. This phenomenon constitutes a nonlinear saturation mechanism for right-hand ...

The study of the stable and the metastable ferroelectric polarization of poly(vinylidene fluoride), PVDF, was performed using two successive equal sign ramp voltages, mediated by a short-circuit period. Rates from 10 V/s ...
