齐次动量空间的场论

Field theories with homogenous momentum space

Florian Girelli, Etera R. Livine

摘要:

讨论动量空间由陪集给出的标量场理论的构造。通过引入广义傅立叶变换,我们展示了对偶标量场理论如何实际存在于斯奈德时空中。作为一个副产品,我们确定了斯奈德的非对易空间的星积实现,但也有必要有这些对称性实现斯奈德的时空庞加莱对称的变形。该构造的一个关键特征是星积是非结合的。

英文摘要:

We discuss the construction of a scalar field theory with momentum space given by a coset. By introducing a generalized Fourier transform, we show how the dual scalar field theory actually lives in Snyder's space-time. As a side-product we identify a star product realization of Snyder's non-commutative space, but also the deformation of the Poincare symmetries necessary to have these symmetries realized in Snyder's space-time. A key feature of the construction is that the star product is non-associative.
