Constant-angle surfaces in liquid crystals [PDF]

open access: yes, 2007
We discuss some properties of surfaces in R3 whose unit normal has constant angle with an assigned direction field. The constant angle condition can be rewritten as an Hamilton-Jacobi equation correlating the surface and the direction field.
