Outline of Final Research Achievements |
A geodesic space is a metric space where geodesics are defined.Geometry of geodesics provides tools to study the topological and geometrical structure of geodesic spaces. Riemannian geometry, Finsler geometry and Alexandrov geometry are those examples.It is not studied systematically the space where distance is non-symmetric in that while it is always interested.I studied each property and theorem known in the symmetric case to get their generalizations and new results in the non-symmetric case by geometry of geodesics.I announced those result as some articles.
