论文摘要
在本文中，我们研究了减速和空间平坦的弗里德曼·莱玛特·罗伯逊 - 罗伯逊 - 罗伯逊 - 宇宙中规定理论的渐近结构。首先，我们在这种背景下彻底探讨了电动力学的渐近对称性，这揭示了平面病例中已经存在的主要不一致。利用这种处理，我们得出了相关的记忆效应，讨论了它们的有效性和差异方面的差异。接下来，我们将分析扩展到非亚洲阳米尔，将其动态和同时耦合到狄拉克旋转器和复杂的标量场。在这种新颖的环境中，我们研究了基于协变相形式的构建泊松超级托架的可能性。
In this paper, we investigate the asymptotic structure of gauge theories in decelerating and spatially flat Friedmann-Lemaître-Robertson-Walker universes. Firstly, we thoroughly explore the asymptotic symmetries of electrodynamics in this background, which reveals a major inconsistency already present in the flat case. Taking advantage of this treatment, we derive the associated memory effects, discussing their regime of validity and differences with respect to their flat counterparts. Next, we extend our analysis to non-Abelian Yang-Mills, coupling it dynamically and simultaneously to a Dirac spinor and a complex scalar field. Within this novel setting, we examine the possibility of constructing Poisson superbrackets based on the covariant phase space formalism.
