Maximum number of limit cycles of cubic Lienard differential system

Applied Mathematical Sciences, 2014
The number of limit cycles of the cubic Lie´nard polynomial differential system of the form x˙ = y, y˙ = - g(x)- f (x)y is examined, where f (x) is a polynomial of degree three and g(x), a polynomial of degree one and two. The accurate upper bound of the maximum number of limit cycles of this Lie´nard differential system is obtained. By using the first
