标题： Lovelock theory and the AdS/CFT correspondence

摘要： 洛伦兹理论是广义相对论在高维空间中的自然延伸。 它也可以被视为引力理论中无鬼场的高曲率修正的一个玩具模型。 它包含一个AdS真空族，这为在AdS/CFT对应框架下更广泛的设置中探索不同的全息方面提供了一个有吸引力的平台。 我们将详细阐述这些特性，并回顾之前关于在施加如单位性、能量正性或因果性等条件时，洛伦兹理论对CFT参数所涉及的约束的研究工作。 显示英文摘要

摘要： Lovelock theory is the natural extension of general relativity to higher dimensions. It can be also thought of as a toy model for ghost-free higher curvature corrections in gravitational theories. It admits a family of AdS vacua, which provides an appealing arena to explore different holographic aspects in a broader setup within the context of the AdS/CFT correspondence. We will elaborate on these features and review previous work concerning the constraints that Lovelock theory entails on the CFT parameters when imposing conditions like unitarity, positivity of the energy or causality.
