On the Hausdorff dimension and Cantor set structure of sliding Shilnikov invariant sets

Matheus G. C. Cunha, Douglas D. Novaes, Gabriel Ponce

The concept of sliding Shilnikov connection has been recently introduced and represents an important notion in Filippov systems, because its existence implies chaotic behavior on a…

On the periodic and antiperiodic aspects of the Floquet normal form

Douglas D. Novaes, Pedro C. C. R. Pereira

Floquet's Theorem is a celebrated result in the theory of ordinary differential equations. Essentially, the theorem states that, when studying a linear differential system with

A Melnikov analysis on a family of second order discontinuous differential equations

Douglas D. Novaes, Luan V. M. F. Silva

This paper aims to provide a Melnikov-like function that governs the existence of periodic solutions bifurcating from period annuli in certain families of second-order discontinuou…

The complete dynamics description of positively curved metrics in the Wallach flag manifold

Leonardo F. Cavenaghi, Lino Grama, Ricardo M. Martins +1

The family of invariant Riemannian manifolds in the Wallach flag manifold is described by three parameters of positive real numbers. By rest…

Existence of a cylinder foliated by periodic orbits in the generalized Chazy differential equation

Jaume Llibre, Douglas D. Novaes, Claudia Valls

The generalized Chazy differential equation corresponds to the following two-parameter family of differential equations \begin{equation*}\label{gcdeq} \dddot x+|x|^q \ddot x+\dfrac…

Invariant tori via higher order averaging method: existence, regularity, convergence, stability, and dynamics

Douglas D. Novaes, Pedro C. C. R. Pereira

Important information about the dynamical structure of a differential system can be revealed by looking into its invariant compact manifolds, such as equilibria, periodic orbits, a…
