WebThe group Spin(3) is isomorphic to the special unitary group SU(2); it is also diffeomorphic to the unit 3-sphere S 3 and can be understood as the group of versors (quaternions with absolute value 1). The connection between quaternions and rotations, commonly exploited in computer graphics, is explained in quaternions and spatial rotations. WebThe fundamental group of S n is trivial. If one knew how the fundamental group of quotients Y = X / A looks like, this could be helpful. Idea 2: The map S O ( n + 1) → S n …
