| Outline of Final Research Achievements |
We investigated large scale geometry, mainly coarse geometry for general proper metric spaces with coarse geometry structure and embedding problems of CAT(0)-groups into the Hilbert space. Then we discovered a good relation between coarse geometry and small scale geometry which is an ordinal geometric topology. I obtained many interesting results with the collaborators, Jozef Kransinkiewicz and Stanislaw Spiez (the Institute of Mathematic, Polish Academy of Science). Our papers have excellent evaluation and we were invited important international conferences of geometric topology. For example, Dubrovnik VIII-Geometric Group Theory and Dynamical Systems, Dubrovnik, Croatia. It is one of traditional and important topology conferences.
Due to our proposal we organized an international meeting of coarse geometry at Wasoeda University. The future speakers are Jerzy Dydak (University of Tennessee, USA)and Stanislaw Spiez. It was a good occasion to exchange hot results and opinions.
