... an orientation on such angles by designating the positive -axis ray as the initial ray and the other ray as the terminal ray. (What does it mean if these rays coincide?) Thus we adopt a dynamic viewpoint: the measure of this angle is determined by how we move from the initial ray to the terminal ray ...

... Proposition 4.3. If there is a continous map v : Sn → Sn such that v(x) ⊥ x for all x ∈ Sn , then the antpodal map is homotopic to the identity. The required homotopy is given by ht (x) := cos(πt)x + sin(πt)v(x) for t ∈ [0, 1]. For S1 note that this homotopy just rotates the circle through π radians ...

Smooth Manifolds
... In the first section of this chapter we describe the first of these structures. A topological manifold is a topological space with three special properties that express the notion of being locally like Euclidean space. These properties are shared by Euclidean spaces and by all of the familiar geomet ...
