中文摘要：

对R（N）上临界增长的二次沲函和约束极沁问题进行了研究，得到了极小点的存在性结果，在对取值S（2）的调和映射的研究中，我们引入了局部弱单调不等式的概念，并证证明了这类弱调和映射几乎与ε-正则性是等价的。我们在满足弱单调不等式的弱调和映射类中研究了各种预给奇性的问题，其中之一的结果是证明了满足弱单调不等式但有无限可数个奇点的弱调和映射的存在性。在对子取值于S（2）的调和映射有很强的联欢系的铁磁链平衡组的研究中，我们证明了对常边值问题，尽管其光滑解唯一，但它存在仅有有限个奇点的解，从而说明了Pohozaev恒等式对具奇性的解不成立。本项目已按预期计划顺利完成，大部分结果已在国外主要杂志上发表成已被接受发表。
