关于极非对易性的一个注记

A Remark on Polar Noncommutativity

Andrew Iskauskas

摘要:

非对易空间已被发现在许多不同的上下文中是有用的。特别是,人们可以使用非对易时空来产生量子化的引力理论。通过函数空间上的Moyal $\star$ -乘积和希尔伯特空间上的修正子之间的识别,人们可以使用Seiberg-Witten映射来产生对这种引力理论的修正。然而,必须注意对易关系的推导。我们检查这种方法的有效性的条件,并确定正确的形式极性非交换性$\mathbb{R}^{2}$。这种方法很容易扩展到更复杂的时空参数化。

英文摘要:

Noncommutative space has been found to be of use in a number of different contexts. In particular, one may use noncommutative spacetime to generate quantised gravity theories. Via an identification between the Moyal $\star$-product on function space and commutators on a Hilbert space, one may use the Seiberg-Witten map to generate corrections to such gravity theories. However, care must be taken with the derivation of commutation relations. We examine conditions for the validity of such an approach, and determine the correct form for polar noncommutativity in $\mathbb{R}^{2}$. Such an approach lends itself readily to extension to more complicated spacetime parametrisations.
