Resumen
Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) 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. 267 41671 403 411 NSF [OISE 0526008] Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) NSF [OISE 0526008] CNPq [CNPq-451778/2008-1]
