TL;DR
This paper explores how non-compact quantum 2D AdS space-time arises in 2D Euclidean quantum gravity under specific boundary conditions related to cosmological constants.
Contribution
It demonstrates the emergence of non-compact quantum AdS space-time from boundary conditions in 2D Euclidean quantum gravity.
Findings
Non-compact quantum 2D AdS space-time can emerge under specific boundary conditions.
The ratio of boundary to bulk cosmological constants determines the space-time geometry.
The results connect boundary cosmological parameters with the global structure of quantum space-time.
Abstract
We show how non-compact (quantum 2d AdS) space-time emerges for specific ratios of the square of the boundary cosmological constant to the cosmological constant in 2d Euclidean quantum gravity.
