AI 中文摘要
弦理论的有效作用量因 underlying 理论的众多对称性而具有高度受限的结构。近期，一种名为广义Bergshoeff-de Roo识别的方法被提出，该方法利用微分同胚、洛伦兹、规范不变性以及T对偶性，在双场理论框架下推导有效作用量中的高阶导数耦合项。此方法已被重新研究并进一步完善，以在标准超引力框架内直接生成耦合项。
英文摘要
The effective action of string theory has a highly constrained structure due to the numerous symmetries of the underlying theory. Recently, a method known as the Generalized Bergshoeff-de Roo identification was developed, which exploits diffeomorphism, Lorentz and gauge invariance, along with T-duality, to derive higher-derivative couplings in the effective action within the framework of Double Field Theory. This method has been revisited and further refined to generate couplings directly within the standard Supergravity framework.
