WebJan 19, 2024 · The dual description of a Euclidean black hole is that of a CFT living on a manifold, whose temperature determines the manifold in question. The basic problem with superposing 2 BHs with different masses here is that they would belong to two different CFTs, and you cannot add vectors from two different Hilbert spaces like that. Bruce Lee WebA more general worry about representing inﬂation in AdS/CFT is that the boundary CFT must encode a very large number of degrees of freedom describing the inﬂating region. Speciﬁcally, the authors of [34,35] have pointed out that in certain situations the dS entropy of the inﬂating region is larger than the entropy of the Schwarzschild ... ignited petrol fire extinguisherWebBoundary conformal ﬂeld theory2 1 Review of CFT 1.1 Stress tensor and Ward identities Two-dimensionalCFTsaremassless, local, relativisticrenormalizedquantum ﬂeld theories.

WebThe whole subject of boundary CFT was founded by Cardy, who almost single-handedly pushed its development very far. His works [98–100] still provide an excellent introduction, together with papers by Ishibashi [294] and [102, 334] by Cardy and Lewellen.

Nevertheless, a bulk analysis suggests that certain such flows lead to local CFTs in the infra-red.
