从Wilson的观点来看，可重整化理论被理解为理论空间中的子流形，它起源于重整化群演化下的一个特定的不动点。我们展示了这幅图如何精确地应用于它们的引力场。我们研究了Wilson作用量所满足的Hamilton-Jacobi方程，找到了相应的不动点及其本征变形，它们在不动点附近有一个对角演化.相关的本征变形被用来构建重整化理论。我们探讨这种形式主义与全息重整化的关系。我们还讨论了不同的重正化方案，并表明重力运动方程的解决方案可以作为参数化重正化理论的重正化耦合。这提供了一个透明的连接全息重整化群流在威尔逊和非威尔逊的方法。一般的结果说明了显式计算中的相互作用标量理论在AdS空间。
A bstractFrom the Wilsonian point of view, renormalisable theories are understood as submanifolds in theory space emanating from a particular fixed point under renormalisation group evolution. We show how this picture precisely applies to their gravity duals. We investigate the Hamilton-Jacobi equation satisfied by the Wilson action and find the corresponding fixed points and their eigendeformations, which have a diagonal evolution close to the fixed points. The relevant eigendeformations are used to construct renormalised theories. We explore the relation of this formalism with holographic renormalisation. We also discuss different renormalisation schemes and show that the solutions to the gravity equations of motion can be used as renormalised couplings that parametrise the renormalised theories. This provides a transparent connection between holographic renormalisation group flows in the Wilsonian and non-Wilsonian approaches. The general results are illustrated by explicit calculations in an interacting scalar theory in AdS space.
