Local bifurcations in a class of piecewise-smooth Filippov systems with a nonregular switching curve via a nonlinear double regularization process

Claudio A. Buzzi, Yagor Romano Carvalho

We are interested in analyzing the preservation of bifurcations in a class of piecewise smooth vector fields with a nonregular switching set under a smoothing process that approxim…

Piecewise Smooth Dynamical Systems Regularized by Convolution

Claudio A. Buzzi, Daniel Panazzolo, Paulo R. da Silva

We present a general regularization procedure for piecewise smooth vector fields whose discontinuity locus is a variety of normal crossings type. We show that such regularization c…

A note on a recent attempt to solve the second part of Hilbert's 16th Problem

Claudio A. Buzzi, Douglas D. Novaes

For a given natural number , the second part of Hilbert's 16th Problem asks whether there exists a finite upper bound for the maximum number of limit cycles that planar polynomi…
