Classification of rotational surfaces in Euclidean space satisfying a linear relation between their principal curvatures

Rafael López, Álvaro Pámpano

Mathematische Nachrichten > 293 > 4 > 735 - 753

We classify all rotational surfaces in Euclidean space whose principal curvatures κ₁ and κ₂ satisfy the linear relation

κ_{1} = a κ_{2} + b

, where a and b are two constants. As a consequence of this classification, we find closed (embedded and not embedded) surfaces and periodic (embedded and not embedded) surfaces with a geometric behaviour similar to Delaunay surfaces. Finally, we give a variational characterization...
