Outline of Annual Research Achievements

本年度も昨年度に引き続き、負曲率性や非正曲率性を何らかの意味で有する非有界な距離空間や無限離散群を、粗幾何的観点、非可換幾何的観点、力学系的観点から研究を行い、広島および中国の重慶で研究発表を行った。

また、「Yoshifumi Matsuda; Shin-ichi Oguni; Saeko Yamagata, Notes on relatively hyperbolic groups and relatively quasiconvex subgroups, Tokyo Journal of Mathematics」「Tomohiro Fukaya; Shin-ichi Oguni, Coronae of product spaces and the coarse Baum-Connes conjecture, Advances in Mathematics」「Tomohiro Fukaya; Shin-ichi Oguni, The coarse Baum-Connes conjecture for Busemann non-positively curved spaces, Kyoto Journal of Mathematics」「Tomohiro Fukaya; Shin-ichi Oguni, Coronae of relatively hyperbolic groups and coarse cohomologies, Journal of Topology and Analysis」の4本の論文が出版された。

研究期間全体を通じて、相対的双曲群など、何らかの意味で負曲率性あるいは非正曲率性を有する距離空間および離散群をその境界およびそれへの作用を通じて研究し、様々な知見を得、これらの研究成果を講演で発表し、また、学術論文として出版した。
