Differential Geometric Aspects of Alexandrov Spaces

  title={Differential Geometric Aspects of Alexandrov Spaces},
  author={Y. Otsu},
We summarize the results on the differential geometric structure of Alexandrov spaces developed in [Otsu and Shioya 1994; Otsu 1995; Otsu and Tanoue a]. We discuss Riemannian and second differentiable structure and Jacobi fields on Alexandrov spaces of curvature bounded below or above.
