| Outline of Final Research Achievements |
We introduced the notion of two-point homogeneous quandles, which is an analogy of the notion of two-point homogeneous Riemannian manifolds, and classified those with finite cardinality (The prime cardinality case has been completed by the Principal Investigator, and other case by a Research Partner). We also defined the notion of flat quandles, and classified finite connected ones. The notion of flatness was not defined by curvatures, but a characterization of flat Riemannian symmetric spaces in terms of the transformation groups.
