Piecewise-Smooth Slow–Fast Systems
(2020-01-01)
We deal with piecewise-smooth differential systems ż= X(z) , z= (x, y) ∈ ℝ× ℝn − 1, with switching occurring in a codimension one smooth surface Σ. A regularization of X is a 1-parameter family of smooth vector fields Xδ,δ ...
Design de moda: fast fashion x slow fashion.
(Grupo de Pesquisa VirtuHab, 2017-05-03)
The article, based on research for Doctoral thesis in Design, discusses the complex relationship
between the fashion system and sustainability issues. The environmental impact of the ephemeral
life cycle of fashion ...
Geometric Singular Perturbation Theory for Systems with Symmetry
(2020-01-01)
In this paper we focus on a class of symmetric vector fields in the context of singularly perturbed fast-slow dynamical systems. Our main question is to know how symmetry properties of a dynamical system are affected by ...
Analysis of slow- and fast-alpha band asymmetry during performance of a saccadic eye movement task: Dissociation between memory- and attention-driven systems
(ELSEVIER SCIENCE BVAMSTERDAM, 2013-08-02)
This study aimed at analyzing the relationship between slow- and fast-alpha asymmetry within frontal cortex and the planning, execution and voluntary control of saccadic eye movements (SEM), and quantitative electroencephalography ...

Relaxation oscillation in planar discontinuous piecewise smooth fast–slow systems
(2022-01-01)
This paper provides a geometric analysis of relaxation oscillations in the context of planar fast–slow systems with a discontinuous right-hand side. We give conditions that guarantee the existence of a stable crossing limit ...
Slow–fast systems and sliding on codimension 2 switching manifolds
(2019-01-01)
In this work, we consider piecewise smooth vector fields X defined in R n \ ∑, where Σ is a self-intersecting switching manifold. A double regularization of X is a 2-parameter family of smooth vector fields X ε.η , ε,η > ...
