Anomalies at the End of the Universe?

The spatial distribution of anomalies in extra dimensional theories on a slice of AdS leads to a puzzle where anomalies may not match across different geometries that are dual to various states of the same CFT. We argue that consistency of the anomaly across such geometries necessitates the addition of topological terms or other bulk fermions to the theory that flow any IR localized consistent anomaly into the ``UV" region of these geometries if one wishes to have such a dual interpretation.

Holographic complexity of the Klebanov-Strassler background

We study the complexity of the gravity dual to the confining $SU(N)\times SU(N+M)$ Klebanov-Strassler gauge theory, which is an important test case for holographic complexity in higher-dimensional and nonconformal gauge/gravity dualities. We emphasize the dependence of the complexity on parameters of the gauge theory, finding a common behavior with confinement scale for several complexity functionals. We also analyze how the complexity diverges with the UV cut off, which is more complicated than in AdS backgrounds because the theory is nonconformal. Our results may provide new perspectives on questions in the holographic complexity program as well as a starting point for further studies of complexity in general gauge/gravity dualities.
