abstract = {<p style="text-align: justify;">The Hopf cyclicities of some smooth polynomial, rational polynomial and piecewise smooth Liénard systems are studied. For two Liénard
systems with the same damping term and different restoring (or potential)
terms, we provide sufficient conditions that the two systems have the same
Hopf cyclicity. Then, some examples are given to illustrate the efficiency and
applicability of our results.</p>},
