论文摘要
渐近安全是量子场理论的紫外线完成的理论建议，尤其是量子重力。该程序的重大进展导致了路透定时点的首次表征。我们对量子时空性质的理解进一步发展需要解决许多开放问题和挑战。在这里，我们的目的是在渐近安全计划中对最新技术的批判性思考，并在技术和概念性的开放性问题上指定和阐述。我们还指出了在实施的各个阶段的系统途径，以回答它们。最后，我们还借此机会澄清了有关该计划的一些常见误解。
Asymptotic safety is a theoretical proposal for the ultraviolet completion of quantum field theories, in particular for quantum gravity. Significant progress on this program has led to a first characterization of the Reuter fixed point. Further advancement in our understanding of the nature of quantum spacetime requires addressing a number of open questions and challenges. Here, we aim at providing a critical reflection on the state of the art in the asymptotic safety program, specifying and elaborating on open questions of both technical and conceptual nature. We also point out systematic pathways, in various stages of practical implementation, towards answering them. Finally, we also take the opportunity to clarify some common misunderstandings regarding the program.
