Dupin hypersurface
In differential geometry, a Dupin hypersurface is a submanifold in a space form, whose principal curvatures have globally constant multiplicities.^{[1]}
Application
A hypersurface is called a Dupin hypersurface if the multiplicity of each principal curvature is constant on hypersurface and each principal curvature is constant along its associated principal directions.^{[2]} All proper Dupin submanifolds arise as focal submanifolds of proper Dupin hypersurfaces.^{[3]}
