In [[mathematics]], the '''Gauss map''' for a surface <math>S</math> lying in 3-space, associates to any point <math>p</math> of <math>S</math> the unit (normal) vector <math>N=N(p)</math> that is orthogonal to the tangent plane to <math>S</math> at <math>p</math>. Hence <math>N</math> is a map from <math>S</math> to the unit sphere <math>S^2</math>.
 
=='''A'''==
There arises the question of choosing the normal vector <math>N(p)</math> among the two possible choices (namely <math>N</math> and <math>-N</math>). Moreover we will require the Gauss map to be continuous: no jumps are allowed. There is no a priori "better" choice, however the ability to choose a (continuous) Gauss map is equivalent to the surface being [[orientable]]. However it is always locally true (i.e. on a small piece of the surface).

The notion of Gauss map can be generalized to a submanifold <math>S</math> of dimension <math>k</math> in an ambient manifold <math>M</math> of dimension <math>n</math>. In that case, the unit normal vector is replaced by the tangent <math>k</math>-plane at the point <math>p \in S</math>. (It should be noted that in euclidean 3-space, a 2-plane is characterized by its unit normal vector -- up to sign, hence the definition above.) The Gauss map then goes from <math>S</math> to the set of tangent <math>k</math>-planes in the tangent bundle <math>TM</math>. The situation is somewhat simpler in euclidean <math>n</math>-space, where the target set is the [[Grassmannian]] <math>G_{k,n}</math>: the set of all (oriented) <math>k</math>-planes in <math>\mathbb{R}^n</math>. (In the introductory example, <math>G_{2,3} \simeq G_{1,3} \simeq S^2</math>.) In a more general manifold <math>M</math>, the target space for the Gauss map <math>N</math> is a Grassmann bundle built on the tangent bundle <math>TM</math>. The question of the (global) existence of <math>N</math> is then a non trivial topological question.
