| Outline of Final Research Achievements |
I submitted my paper: "On real anti-bicanonical curves with one double point on the 4-th real Hirzebruch surface" to Journal of Singularities in 2013. The referee gave me valuable comments and important indications, that is, needlessness of one degeneration which I introduced, and requirements for the marking adapted to the orthogonal decomposition U+<-2>. I revised the paper and submitted it again. It was accepted in May 2014 and published in January 2015. I held Workshops on K3 surfaces and Enriques surfaces every summer during 2013--2015. Participants, including young talented mathematicians working for K3 surfaces and Enriques surfaces, discussed each other.
