Albarakati, W. A.; Lloyd, N. G.; Pearson, J. M. Transformation to Liénard form. (English) Zbl 0983.34023 Electron. J. Differ. Equ. 2000, Paper No. 76, 11 p. (2000). The authors’ abstract: The authors show that certain two-dimensional differential systems can be transformed to a system of Liénard type. This enables known criteria for the existence of a centre for Liénard systems to be exploited, so extending the range of techniques which are available for proving that conditions which are known to be necessary for a centre are also sufficient.
