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.
