Title: Codimension three nonnegatively curved submanifolds with infinite fundamental group
Author: Foss, JN

Abstract: We show that a complete, codimension three submanifold M of nonnegative sectional curvature that isometrically splits as (M) over bar x 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.
