Lie型非对易时空的星积与不变积分

Star Product and Invariant Integration for Lie type Noncommutative Spacetimes

Chryssomalis Chryssomalakos, Elias Okon

摘要:

我们提出了一个明星产品的非交换空间的李型,包括所谓的“规范”的情况下,通过引入一个中心生成器,这是兼容的翻译,并承认一个简单的,易于管理的定义的不变积分。一个准循环属性,后者被证明持有,这减少到确切的循环时,伴随表示的基本李代数是无迹的。几个明确的例子说明了形式主义,处理卡帕-闵可夫斯基时空和海森堡代数(“规范”非交换2-平面)。

英文摘要:

We present a star product for noncommutative spaces of Lie type, including the so called ``canonical'' case by introducing a central generator, which is compatible with translations and admits a simple, manageable definition of an invariant integral. A quasi-cyclicity property for the latter is shown to hold, which reduces to exact cyclicity when the adjoint representation of the underlying Lie algebra is traceless. Several explicit examples illuminate the formalism, dealing with kappa-Minkowski spacetime and the Heisenberg algebra (``canonical'' noncommutative 2-plane).
