| Limit cycles in Liénard equations |
The talk will deal with (generalized) polynomial Liénard equations,
i.e. 2-dimensional differential equations coming from second
order scalar equations
, with P and Q polynomials. Depending on the degree of Pand Q there are results concerning the number of limit cycles which
such systems can have in the phase plane. We will present some of
these results and discuss some open problems.
