A new construction for Melnikov chaos in piecewise-smooth planar systems
Alessandro Calamai, Matteo Franca, Michal Pospisil
In this paper we consider a piecewise smooth -dimensional system \[ \dot{\vec{x}}=\vec{g} (\vec{x})+\varepsilon\vec{g}(t,\vec{x},\varepsilon) \] where is a small…

A bifurcation phenomenon for the critical Laplace and -Laplace equation in the ball
Francesca Dalbono, Matteo Franca, Andrea Sfecci
In this paper we show that the number of radial positive solutions of the following critical problem …
