英文摘要
I have obtained some results on CAT(0) groups, CAT(0) spaces, their boundaries and Coxeter groups. First, I proved a "splitting theorem" for CAT(0) spaces, and obtained that products of rigid CAT(0) groups are also rigid CAT(0). Next, I had some results on equivariant-homeomorphisms of boundaries of CAT(0) groups. Also I obtained results on algebraic rigidity of Coxeter groups and on graph theory by investigating corresponding Coxeter groups.
