On the number of limit cycles in discontinuous piecewise linear differential systems with two pieces separated by a straight line
Rodrigo D. Euzébio, Jaume Llibre
In this paper we study the maximum number of limit cycles that can exhibit a planar piecewise linear differential system formed by two pieces separated by a straight line. More…
Radii of starlikeness and convexity of some -Bessel functions
Árpád Baricz, Dimitar K. Dimitrov, István Mező
Geometric properties of the Jackson and Hahn-Exton -Bessel functions are studied. For each of them, three different normalizations are applied in such a way that the resulting f…
Radii of starlikeness of some special functions
Árpád Baricz, Dimitar K. Dimitrov, Halit Orhan +1
Geometric properties of the classical Lommel and Struve functions, both of the first kind, are studied. For each of them, there different normalizations are applied in such a way t…
Para-orthogonal polynomials on the unit circle satisfying three term recurrence formulas
Cleonice F. Bracciali, Alagacone Sri Ranga, Anbhu Swaminathan
When a nontrivial measure on the unit circle satisfies the symmetry then the associated OPUC, say , are all real. In this case, Delsarte a…
Bifurcation of limit cycles from a non-smooth perturbation of a two-dimensional isochronous cylinder
Claudio A. Buzzi, Rodrigo D. Euzebio, Ana C. Mereu
Detect the birth of limit cycles in non-smooth vector fields is a very important matter into the recent theory of dynamical systems and applied sciences. The goal of this paper is…
Chaotic Planar Piecewise Smooth Vector Fields With Non Trivial Minimal Sets
Claudio Buzzi, Tiago de Carvalho, Rodrigo Euzebio
In this paper some aspects on chaotic behavior and minimality in planar piecewise smooth vector fields theory are treated. The occurrence of non-deterministic chaos is observed and…
Zero-Hopf bifurcation in a Chua system
Jaume Llibre, Rodrigo Euzebio
A zero-Hopf equilibrium is an isolated equilibrium point whose eigenvalues are and . In general for a such equilibrium there is no theory for knowing when from it…
Zero-Hopf bifurcation in the FitzHugh-Nagumo system
Claudio Vidal, Jaume Llibre, Rodrigo Euzebio
We characterize the values of the parameters for which a zero--Hopf equilibrium point takes place at the singular points, namely, (the origin), and in the FitzHugh-…
Periodic Solutions of the extended Duffing-Van der Pol Oscillator
Rodrigo Euzebio, Jaume Llibre
In this paper some aspects on the periodic solutions of the extended Duffing-Van der Pol oscillator are discussed. Doing different rescaling of the variables and parameters of the…
