Biharmonic Legendre Curves on Totally η-Umbilical, Ruled, and Hopf Hypersurfaces in Four-Dimensional Complex Space Forms

Symmetry
The main purpose of the present paper is to investigate biharmonic Legendre curves on hypersurfaces in four-dimensional complex space forms. We examine the necessary conditions for the existence of such curves on totally η-umbilical, ruled, and Hopf hypersurfaces for which the shape operator AN satisfies a symmetry property.
