标题： Time-dependent microstrata in AdS3

摘要： 我们使用微扰理论构建一族时间依赖的微观结构：一组非极端的IIB超引力解，其渐近于$AdS_3 \times S^3 \times T^4$。 我们的构造表明，arXiv:2307.13021中的“特殊位置”约束可以通过允许解依赖于时间而被打破。 我们研究微扰理论中出现的长期项。 其中一些可以重新求和为频率偏移，其解释与之前研究的微观结构解相同。 其他长期项更难重新求和，这质疑了这些解的长期稳定性。 显示英文摘要

摘要： We use perturbation theory to construct a family of time-dependent microstrata: a set of non-extremal solutions of IIB supergravity asymptotic to $AdS_3 \times S^3 \times T^4$. Our construction shows that the "special locus" constraints of arXiv:2307.13021 can be broken by allowing the solutions to depend on time. We study the secular terms appearing in the perturbation theory. Some of them can be resummed into frequency shifts, with the same interpretation as for the previously-studied microstrata solutions. Other secular terms appear harder to resum, questioning the long-term stability of the solutions.
