Is covariant star product unique?

High Energy Physics - Theory 2011-01-25 v1

Abstract

We give a nontechnical introduction to the problem of non-uniqueness of star products and describe a covariant resolution of this problem. Some implications (e.g., for noncommutative gravity) and further prospects are discussed.
