Resumo

In this work we give a characterization of pseudo-parallel surfaces in S(c)(n)xR and H(c)(n)xR, extending an analogous result by Asperti-Lobos-Mercuri for the pseudo-parallel case in space forms. Moreover, when n = 3, we prove that any pseudo-parallel surface has flat normal bundle. We also give examples of pseudo-parallel surfaces which are neither semi-parallel nor pseudo-parallel surfaces in a slice. Finally, when n = 4 we give examples of pseudo-parallel surfaces with non vanishing normal curvature. (AU)
