在过去的二十年里，引力渐近安全方案经历了一个重大的转变，从一个奇异的可能性，成为一个现实的量子引力理论的有力竞争者。它的目标是在量子场论的范围内对引力相互作用和时空几何进行数学上一致的量子描述，这使其预测能力保持在最高能量。本卷提供了一个独立的教学介绍渐近安全，并介绍了在其调查中使用的功能重整化群技术，沿着与必要的计算技术。在基础章节之后是迄今为止取得的成果的可访问摘要。这是第一次详细阐述渐近安全性，提供了一个独特的介绍量子引力，它假设没有以前熟悉重整化群。它作为一个重要的资源，为实践研究人员和研究生进入这个成熟的领域。
During the past two decades the gravitational asymptotic safety scenario has undergone a major transition from an exotic possibility to a serious contender for a realistic theory of quantum gravity. It aims at a mathematically consistent quantum description of the gravitational interaction and the geometry of spacetime within the realm of quantum field theory, which keeps its predictive power at the highest energies. This volume provides a self-contained pedagogical introduction to asymptotic safety, and introduces the functional renormalization group techniques used in its investigation, along with the requisite computational techniques. The foundational chapters are followed by an accessible summary of the results obtained so far. It is the first detailed exposition of asymptotic safety, providing a unique introduction to quantum gravity and it assumes no previous familiarity with the renormalization group. It serves as an important resource for both practising researchers and graduate students entering this maturing field.
