EAElba Alonso-MonsalveDHDaniel HarlowPJPatrick O. Jefferson

Key Points

  • The aim is to construct the classical phase space of Jackiw-Teitelboim gravity with a positive cosmological constant.
  • Constructed phase space on spatial slices with circle topology.
  • Analyzed singular points of the phase space.
  • Explored group-theoretic descriptions pertinent to quantization.
  • Identified that the phase space has many singular points.
  • Noted the phase space is not Hausdorff.
  • Established a viable group-theoretic description for quantization.

Abstract

A bstract In this paper we construct the classical phase space of Jackiw-Teitelboim gravity with positive cosmological constant on spatial slices with circle topology. This turns out to be somewhat more intricate than in the case of negative cosmological constant; this phase space has many singular points and is not even Hausdorff. Nonetheless, it admits a group-theoretic description which is quite amenable to quantization.
