The group approach to AdS space propagators
Thorsten Leonhardt, Ruben Manvelyan, Werner Ruehl
TL;DR
This paper presents a method to compute AdS two-point functions by connecting interior points through boundary-to-bulk intertwiners, simplifying calculations in AdS space.
Contribution
It introduces a novel approach using Dobrev's boundary-to-bulk intertwiners to derive AdS propagators via boundary integration.
Findings
AdS two-point functions can be constructed from boundary-to-bulk intertwiners.
The method simplifies the calculation of propagators in AdS space.
Provides a new perspective on the boundary-bulk relationship in AdS/CFT.
Abstract
We show that AdS two-point functions can be obtained by connecting two points in the interior of AdS space with one point on its boundary by a dual pair of Dobrev's boundary-to-bulk intertwiners and integrating over the boundary point.
