论文摘要
我们讨论了简单4D量子引力的小组现场理论模型的重新规定分析的动机和目标，并简要审查了该研究领域的状态。我们提出了一些扰动GFT（旋转泡沫）振幅的新计算，特别是在辐射校正对N点功能的缩放行为。最后，我们挑出关键的开放问题，并建议许多研究方向，以在该领域进一步进步。
We discuss motivation and goals of renormalization analyses of group field theory models of simplicial 4d quantum gravity, and review briefly the status of this research area. We present some new computations of perturbative GFT (spin foam) amplitudes, concerning in particular the scaling behaviour of radiative corrections to N-point functions. Finally, we single out key open issues and suggest a number of research directions for further progress in this area.
