2020-06-13 · The notion of Orientation is a formalization and far-reaching generalization of the concept of direction on a curve. The orientation of special classes of spaces is defined (cf. Manifold ; Vector bundle ; Poincaré complex, etc.). The modern view of orientation is given in Generalized cohomology theories .

In many books (say Tu or even Guillemin-Pollack) an orientation on a manifold is an assignment to affix $+1$ and $-1$ to classes of (tangent) basis. It is proven in nearly every differential geometry book that connected orientable manifolds admits exactly two orientations. An oriented manifold is a (necessarily orientable) manifold M endowed with an orientation. If (M, 𝔬) is an oriented manifold then 𝔬 ⁢ (1) is called the fundamental class of M, or the orientation class of M, and is denoted by [M]. Let be a -dimensional topological manifold. We construct an oriented manifold and a -fold covering called the orientation covering. The non-trivial deck transformation of this covering is orientation-reversing.
