✦ Synopsis


This article presents a new method for determining the Liapunov quantities of Li4nard systems with either cubic damping or restoring terms. The first eleven quantities have been computed on a PC, whereas the algorithm used previously requires the use of high powered computers with lots of memory. The reduction part of the algorithm is simplified by expressing the Liapunov quantities in a special form. The maximum number of small-amplitude limit cycles which may be bifurcated from the origin is given for certain systems. (~

In this article we give explicit formulae for the Liapunov quantities of generalized Li@nard systems with either quadratic damping or restoring coefficients. These quantities provide necessary conditions in order for the origin to be a centre. Recent results are also presented for these systems.
