Abstract
The problem of uniqueness of limit cycles for the Liénard equation x¨+f(x)x˙+g(x) =0 is investigated. The classical assumption of sign-definiteness of f(x) is relaxed. The effectiveness of our result as a perturbation technique is illustrated by some constructive examples of small amplitude limit cycles, coming from bifurcation theory.File in questo prodotto:
