OverviewHigh Quality Content by WIKIPEDIA articles! In geometry, a Catalan surface, named after the Belgian mathematician Eugene Charles Catalan, is a ruled surface all of whose rulings are parallel to a fixed plane. The vector equation of a Catalan surface is given by r = s(u) + v L(u), where r = s(u) is the space curve and L(u) is the unit vector of the ruling at u = u. All the vectors L(u) are parallel to the same plane, called the directrix plane of the surface. This can be characterized by the condition: the mixed product [L(u), L' (u), L (u)] = 0.
