The Braided Quantum 2-Sphere
In a recent paper the quantum 2-sphere was described as a quantum
complex manifold. Here we consider several copies of and derive their
braiding commutation relations. The braiding is extended to the differential
and to the integral calculus on the spheres. A quantum analogue of the
classical anharmonic ratio of four points on the sphere is given, which is
invariant under the coaction of .Comment: 14 page
