摘要
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 ,并改进了
The solvability of the second-order nonlinear differential equation with multiple-point boundary value conditions at resonance is discussed by means of the coincidence degree theory of Mawhin, on the basis of which the results of Gupta et al are improved.
