Snyder模型在弯曲空间上的推广

Generalizations of Snyder model to curved spaces

S. Meljanac, S. Mignemi

摘要:

我们考虑推广的Snyder代数的弯曲时空背景与德西特对称性。作为特例,我们得到了杨模型和三重狭义相对论的代数。我们讨论这些代数的实现规范相空间坐标,高达四阶的变形参数。在三重狭义相对论的情况下,利用其与斯奈德模型的代数关系,我们也找到了精确的实现。

英文摘要:

We consider generalizations of the Snyder algebra to a curved spacetime background with de Sitter symmetry. As special cases, we obtain the algebras of the Yang model and of triply special relativity. We discuss the realizations of these algebras in terms of canonical phase space coordinates, up to fourth order in the deformation parameters. In the case of triply special relativity we also find exact realization, exploiting its algebraic relation with the Snyder model.
