Which is the smooth or surface?
A surface is said to be smooth if it does not have singular points, in other words, if it has a (unique) tangent plane at every point. For this we need to clarify if the surface is considered from a real affine, a real projective, or a complex projective point of view, the conditions becoming stronger and stronger.
