Nonuniqueness of Green’s functions at special points
Abstract We investigate a new property of retarded Green’s functions using AdS/CFT. The Green's functions are not unique at special points in complex momentum space. This arises because there is no unique incoming mode at the horizon and is similar to the “pole skipping” phenomenon in holograp...
