Abstract
In this paper, we consider the hypersurfaces of Randers space with constant flag curvature. (1) Let \(({\overline M ^{n + 1}},\overline F )\) be a Randers-Minkowski space. If (Mn, F)isa hypersurface of \(({\overline M ^{n + 1}},\overline F )\) with constant flag curvature K = 1, then we can prove that M is Riemannian. (2) Let \(({\overline M ^{n + 1}},\overline F )\) be a Randers space with constant flag curvature. Assume (M, F) is a compact hypersurface of \(({\overline M ^{n + 1}},\overline F )\) with constant mean curvature ∣H∣. Then a pinching theorem is established, which generalizes the result of [Proc. Amer. Math. Soc., 120, 1223–1229 (1994)] from the Riemannian case to the Randers space.
