Characterizations of space forms by circles on their geodesic spheres. (English) Zbl 1030.53057

Proc. Japan Acad., Ser. A 78, No. 7, 143-147 (2002).
Starting from the previous work of the authors [Bull. Aust. Math. Soc. 62, No. 2, 205-210 (2000; Zbl 0978.53071)] where the space forms are characterized in terms of the extrinsic shape of geodesics in geodesic spheres, in this paper, the authors extend the obtained results by using circles on their geodesic spheres.
