Invariant star-products on S2 and the canonical trace
Abstract
In the literature there are two different ways of describing an invariant star product on S2. We show that the products are actually the same. We also calculate the canonical trace and use the Fedosov-Nest-Tsygan index theorem to obtain the characteristic class of this product.
