The generic unfolding of a codimension-two connection to a two-fold singularity of planar Filippov systems
Douglas Duarte Novaes, Marco Antonio Teixeira, Iris de Oliveira Zeli
Generic bifurcation theory was classically well developed for smooth differential systems, establishing results for -parameter families of planar vector fields. In the present s…
Nonlinear Sliding of Discontinuous Vector Fields and Singular Perturbation
Paulo Ricardo da Silva, Ingrid Sofia Meza-Sarmiento, Douglas Duarte Novaes
We consider piecewise smooth vector fields (PSVF) defined in open sets with switching manifold being a smooth surface . The PSVF are given by pairs $X = (X_+, X…
A note on invariant measures for Filippov systems
Douglas Duarte Novaes, Régis Varão
We are interested in Filippov systems which preserve a probability measure on a compact manifold. We define a measure to be invariant for a Filippov system as the natural analogous…
Asymptotic behavior of periodic solutions in one-parameter families of Liénard equations
Pedro Toniol Cardin, Douglas Duarte Novaes
In this paper, we consider one--parameter () families of Liénard differential equations. We are concerned with the study on the asymptotic behavior of periodic solutions for s…
