The angles relevant to this work are the point angles 0 < ξ < π/2 of the infinite dimensional theory [13], together with the corresponding subspaces (principal modes) and their orthogonal complements (bi-orthogonal modes).

Complete sets of functions exist on surfaces (Lyapunov surfaces) that are mathematically characterized by three conditions: the normal is well defined at every point; the angle between the normals at any two points on the surface is bounded from above by a function of the distance between these points; all the lines parallel to a normal at an arbitrary point on the surface intercept only once the patches of surface contained in balls centered at the point and smaller than a critical value [18].
