Research output: Contribution to journalArticlepeer-review


Witten has presented an argument for the vanishing of the cosmological constant in 2 + 1 dimensions. This argument is crucially tied to the specific properties of (2 + 1)-dimensional gravity. We argue that this reasoning can be deconstructed to 3 + 1 dimensions under certain conditions. Our observation is also tied to a possibility that there exists a well-defined UV completion of (3 + 1)-dimensional gravity.
