Note that when the Hopf action preserves the filtration of B, Theo-rem 1.2 (even without the PI reduction assumption) is proved in [EW1, 1It follows from Lemma 2.1(ii) below that if this condition holds for one pair (R,B R), then the condition holds for all such pairs.
Sub-riemannian geometry of the p;q Hopf actions
The Hopf mapping maps the rotation to the point on the 2-sphere given by θ and φ, and the associated circle is parametrized by ψ. Note that when θ = π the Euler angles φ and ψ are not well defined individually, so we do not have a one-to-one mapping (or a one-to-two mapping) between the 3 … Meer weergeven In the mathematical field of differential topology, the Hopf fibration (also known as the Hopf bundle or Hopf map) describes a 3-sphere (a hypersphere in four-dimensional space) in terms of circles and an ordinary sphere. … Meer weergeven The Hopf construction, viewed as a fiber bundle p: S → CP , admits several generalizations, which are also often known as Hopf fibrations. First, one can replace the … Meer weergeven 1. ^ This partition of the 3-sphere into disjoint great circles is possible because, unlike with the 2-sphere, distinct great circles of the 3-sphere need not intersect. 2. ^ … Meer weergeven For any natural number n, an n-dimensional sphere, or n-sphere, can be defined as the set of points in an $${\displaystyle (n+1)}$$-dimensional space which are a fixed distance … Meer weergeven The Hopf fibration has many implications, some purely attractive, others deeper. For example, stereographic projection S → R induces a remarkable structure in R , which in turn illuminates the topology of the bundle (Lyons 2003).
