Surfaces of a Euclidean space with helical or planar geodesics through a point
Helical curves are such with constant Frénet curvatures. Helical submanifolds are those, for which all geodesics are helical, and these were frequently studied. In the present paper the author assumes that only the geodesics through some fixed point are helical or planar, and obtains several classification results for low codimension.
