Geometry on real closed fields and sevaral complex variable functions

我和雷恩大学的Fichou一起研究了两个问题。一个是奇点理论中关于解析函数芽分类的公开问题，另一个是关于Milnor纤维的问题。第一篇已经发表在一本杂志上，我们正在写第二篇。我们解决了一个著名的问题上的一个拓扑版本的阿廷逼近定理。我们现在正在写它。我还与兵库教育大学的小池和琦玉大学的福井合作。解决了真实的奇点理论中的两个问题。一个已经出版，另一个将被写入。

I worked with Fichou of University of Rennes on two problems. One problem is an open problem of singularity theory on classifications of analytic function germs, and the other is about Milnor fibers. The first was already published in a journal, and we are writing the second.I worked with Tressl of Manchester Universuty. We solved a well known problem on a topological version of Artin approximation theorem. We are now writing it.I also worked with Koike of Hyogo University of education and Fukui of Saitama University. We solved two problems on real singularity theory. One was published, and the other will be written.
