无限远奇点论文文献综述
董金柱[1]（1957）在《范·特·坡方程式的无限远奇点》一文中研究指出The point at infinity of the phase-plane of van der Pol's equation being transformed into the origin of the plane by an inversion, shews itself as an unstable node when regarded as a singular point. Hence, there are exactly two singular points in the closed plane. The fact that the behavior of these two points gives at least a stable limit cycle is then an immediate consequence of the Poincare-Bendixson Theorem. The limiting position of P for λ→∞ is shewn at the end of the present paper to be two lines parallel to the ordinate axis in the phase-plane.(本文来源于《清华大学学报(自然科学版)》期刊1957年01期）
