| Research Abstract |
We studied :
(K.Yokoi)
1. the relation between transitivity and strong transitivity for graph self-maps,
2. a Barge-Martin type theorem for graph self-maps for which the set of periodic points is dense,
(T.Hosaka)
3. the interior of the limit set of a group acting on a hyperbolic or CAT(0) space,
4. dense subsets of the boundary of a Coxeter groups,
5. Coxeter systems with two-dimensional Davis-Vinberg complexes,
6. strong rigidity and strong reflection rigidity of Coxeter systems of dihedral gropus,
7. boundaries of parabolic subgroups of Coxeter groups,
8. the minimality of the boundary of a Coxeter systems,
9. reflection groups of geodesic spaces,
(M.Kimura)
10. congruent classes of Frenet curves of order 2 in the complex quadric,
11. the possibility of different presentations of spaces as unions or partitions of locally compact subspaces, and
(Y.Hattori)
12. there is no upper bound of small transfinte compactness degree in metrizable spaces.
