S. Meljanac, D. Meljanac, S. Mignemi, R. Štrajn

摘要:

我们讨论了概括的斯奈德模型,其中包括所有可能的变形海森堡代数兼容洛伦兹不变性,在实现的非交换几何。相应的变形动量,扭曲和$R$ -矩阵的增加计算到一阶的变形参数的所有模型。在Snyder实现的特殊情况下,得到了扭转的精确公式。

英文摘要:

We discuss a generalisation of the Snyder model that includes all the possible deformations of the Heisenberg algebra compatible with Lorentz invariance, in terms of realisations of the noncommutative geometry. The corresponding deformed addition of momenta, the twist and the $R$-matrix are calculated to first order in the deformation parameters for all models. In the particular case of the Snyder realisation, the exact formula for the twist is obtained.
