We call such submanifolds tangentially cubic. We proved that every null 2- type submanifold M of E-m is tangentially cubic. Further, we prove that the pointed helical geodesic surfaces of E-5 with constant Gaussian curvature are tangentially cubic.eninfo:eu-repo/semantics/closedAccessBiharmonic surfacesTangentially cubic surfacesScience & technologyPhysical sciencesMathematicsArticle00043909690001011211732
