On the uniqueness of limit cycle for certain Liénard systems without symmetry

The problem of the uniqueness of limit cycles for Liénard systems is investigated in connection with the properties of the function $F(x)$. When $\alpha$ and $\beta$~$(\alpha<0<\beta)$ are the unique nontrivial solutions of the equation $F(x)=0$, necessary and sufficient conditions in order th...
