| Outline of Final Research Achievements |
Structures of algebraic varieties endowed with A1-fibrations or A2-fibrations have been clarified to a satisfactory level. Structures of those with C*-fibrations have been explored as well. Topology of algebraic varieties as well as their structures is described, and this is one particular aspect of our research.
An international workshop on Algebraic Varieties and Automorphism Groups was held at RIMS of Kyoto University in July, 2014 with more than 20 foreign participants, and its proceedings will be pubplished within the year 2017 as the volume 75 of Advanced Studies in Pure Mathematics of the Mathematical Society of Japan.
