Saddle points and rare collisions under scaling approach in a Fermi accelerator with two nonlinear terms
(2013-04-01)
Rare collisions of a classical particle bouncing between two walls are studied. The dynamics is described by a two-dimensional, nonlinear and area-preserving mapping in the variables velocity and time at the instant that ...

Proximal regularization for the saddle point gradient dynamics
(2021)
This paper concerns the solution of a convex optimization
problem through the saddle point gradient dynamics.
Instead of using the standard Lagrangian as is classical in this
method, we consider a regularized Lagrangian ...

The geometry of quadratic polynomial differential systems with a finite and an infinite Saddle-node (A, B)
(World Scientific Publishing CompanySingapore, 2014-04)
Planar quadratic differential systems occur in many areas of applied mathematics. Although more than one thousand papers have been written on these systems, a complete understanding of this family is still missing. Classical ...
Stability boundary characterization of nonlinear autonomous dynamical systems in the presence of saddle-node equilibrium points
(Sociedade Brasileira de Matemática Aplicada e Computacional, 2012)
A dynamical characterization of the stability boundary for a fairly large class of nonlinear autonomous dynamical systems is developed in this paper. This characterization generalizes the existing results by allowing the ...
The geometry of quadratic polynomial differential systems with a finite and an infinite Saddle-Node (C)
(World Scientific PublishingSingapore, 2015-03)
Planar quadratic differential systems occur in many areas of applied mathematics. Although more than one thousand papers have been written on these systems, a complete understanding of this family is still missing. Classical ...
