Abstract: We show that a complete, codimension three submanifold M of nonnegative sectional curvature that isometrically splits as M̄ × ℝ has nonnegative curvature operator. We apply this result to obtain a classification of codimension three nonflat manifolds of nonnegative sectional curvature and infinite fundamental group. © 2009 Springer-Verlag.
