Abstract:
Let $M$ be a complete hypersurface in ${S^{n + 1}}$ (or ${\mathbf {C}}{P^{n + 1}}$). Assume that through each point $x$ of $M$ a (local) $\mu (x)$-dimensional totally geodesic submanifold ${S_x}$ of ${S^{n + 1}}$ (or ${\mathbf {C}}{P^{n + 1}}$) exists in $M$. A sufficient condition for $M$ itself to be totally geodesic is given in terms of $\mu (x)$.References
