Interview und dokumentarische MethodeIn this work it is shown that, for small β., the system .=., .=±.+α..+.+β.+β..+β.... has at most two limit cycles when α≠(−1/8, ∞)∖{0} (Part II) and also when α<−1/8 (Part III). Part I contains an introduction to the problem, applications of Abelian integrals and some general results.
