运用J.Mawhin迭合度理论研究了2类二阶m点共振边值问题。通过构造Green函数并且赋予f适当的条件,建立了相应边值问题解的存在性和唯一性定理。

英文摘要：

J.Mawhin coineidence degree theory was used to study two kinds of second-order m-point boundary value problems at resonance on infinite interval.By constructing Green function and equipping f with some proper conditions,the existence and uniqueness theorems were established for corresponding boundary value problems.
