Dynamical Noncommutative Spheres
We introduce a family of noncommutative 4-spheres, such that the instanton projector has its first Chern class trivial: ch1(e) = Bχ + bξ. We construct for them a 4-dimensional cycle and calculate explicitly the Chern-Connes paring for the instanton projector.
متن کاملNoncommutative Spheres and Instantons
We report on some recent work on deformation of spaces, notably deformation of spheres, describing two classes of examples. The first class of examples consists of noncommutative manifolds associated with the so called θ-deformations which were introduced in [17] out of a simple analysis in terms of cycles in the (b,B)-complex of cyclic homology. These examples have non-trivial global features ...
متن کاملQuantum Isometries and Noncommutative Spheres
We introduce and study two new examples of noncommutative spheres: the half-liberated sphere, and the free sphere. Together with the usual sphere, these two spheres have the property that the corresponding quantum isometry group is “easy”, in the representation theory sense. We present as well some general comments on the axiomatization problem, and on the “untwisted” and “non-easy” case.
متن کاملNoncommutative Balls and Mirror Quantum Spheres
Noncommutative analogues of n-dimensional balls are defined by repeated application of the quantum double suspension to the classical low-dimensional spaces. In the ‘even-dimensional’ case they correspond to the Twisted Canonical Commutation Relations of Pusz and Woronowicz. Then quantum spheres are constructed as double manifolds of noncommutative balls. Both C-algebras and polynomial algebras...
