Abstract:

The main result is that if $M = {M^n}$ is a complete Riemann manifold of nonnegative sectional curvature and $X: M \to {R^{n + 1}}$ is an isometric immersion such that $X(M)$ has a positive constant mth mean curvature, then $X(M)$ is the product of a Euclidean space ${R^{n - d}}$ and a d-dimensional sphere, $m \leqslant d \leqslant n$.
