Abstract

In this talk it will be present some results over the study on the limit cycles for differential equations that could be written in the following way:
$(\phi (x\prime ))\prime +f(x)\psi (x\prime )+g(x)=0.$
The techniques used in our work introduce some differences from the study of the classical Liénard-type equations. For example, a non-differentiable compactification is very useful in our work.

This is a joint work with Pedro J. Torres (Universidad de Granada) and Joan Torregrosa.
