摘 要: 本文利用Mawhin的连续性定理及迭合度理论,讨论二阶非线性微分方程多点边值问题共振时解的存在性,得到了解存在的充分条件。 The solvability of the second order nonlinear differential equation with multi-point boundary value conditions at resonance is discussed by means of the coincidence degree theory of Mawhin,and the sufficient conditions for the bondary value problems was obtained.
