报告摘要  Abstract

We present a comprehensive introduction to the classical paper by
Hossein Movasati:
Movasati, H./Center conditions: rigidity of logarithmic differential
equations/,/Journal of Differential Equations/, Vol. 197, pp. 197–217
(2004).

We illustrate the fundamental concepts and techniques through the
well-known quadratic case—namely, plane polynomial quadratic systems
with a center—and point out a gap in the proof of Movasati’s theorem.

Finally, we discuss several related open problems.
