DESCRIPTION:Understanding the proper formulation of AdS holography in two
spacetime dimensions has led to fascinating progress in several directions
. The main novel ingredient compared to higher dimensions is that the as
ymptotic behavior of the metric is only "nearly'' AdS in a certain precise
sense. This difference allows for a very simple theory\, Jackiw-Teitelb
oim gravity\, to have a non-perturbative completion as a Hermitian matrix
model. In this talk\, we propose analogous modifications of the flat spa
ce boundary conditions in two dimensional dilaton gravity. These modific
ations allow a very simple theory\, which we call Cangemi-Jackiw gravity\,
to have a non-perturbative completion as a random matrix model. We will
discuss the Lorentzian and Euclidean formulations of this model\, challen
ges in computing its non-perturbative scattering matrix\, and which of its
lessons are potentially applicable to four-dimensional celestial holograp
