Comparison theorems for manifolds with radial curvature bounded below (Q2752889)

This paper is a preliminary draft of recent work of the author with \textit{Y. Itokawa} and \textit{Y. Machigashira} [Proc. 5th Pacific Rim Geometry Conf., Sendai 2000, Tohoku Math. Publ. 20, 61--68 (2001)] on Riemannian manifolds with the radial curvature bounded below. The authors announce the analogues of the Toponogov triangle comparison theorem, the corresponding maximal diameter theorem, and the Bishop-Gromov volume comparison theorem. Proofs are outlined with details to appear elsewhere.NEWLINENEWLINEFor the entire collection see [Zbl 0960.00049].
