Abstract
We perform a Wick rotation and analytic continuation from global AdS to static dS, yielding CFT generators with a nonstandard adjoint action tied to dS bulk coordinates. To reproduce the real-scalar two-point function, we introduce a global defect operator that twists the inner product. We further show that symmetry is spontaneously broken in CFT vacua with a central charge having an imaginary part. Finally, we derive integral identities for bulk and defect correlators, providing a unified framework for computing CFT observables in the presence of global and local defects.
