几乎可换几何的极小扭

Minimal twist of almost commutative geometries

Manuele Filaci, Pierre Martinetti

摘要:

我们对几乎可交换的谱三元组的扭曲进行分类,这些扭曲保持希尔伯特空间和狄拉克算子不变。所涉及的扭曲算子被证明是一个有限维算子,这不一定是一个内部空间的分级的歧管的产品的分级。列出了该算子的必要和充分约束。

英文摘要:

We classify the twists of almost commutative spectral triples that keep the Hilbert space and the Dirac operator untouched. The involved twisting operator is shown to be the product of the grading of a manifold by a finite dimensional operator, which is not necessarily a grading of the internal space. Necessary and sufficient constraints on this operator are listed.
