Ricci and Casorati principal directions of $\delta(2)$ Chen ideal submanifolds
Simona Decu, Anica Pantić, Miroslava Petrović-Torgašev, Leopold Verstraelen
We show that for $\delta(2)$ Chen ideal submanifolds in Euclidean spaces the (intrinsic) Ricci principal directions and the (extrinsic) Casorati principal directions coincide.
