Description
I will discuss three interrelated gravitational models in 1+1 dimensions: Jackiw-Teitelboim (JT) gravity, double-scaled SYK, and Liouville gravity. In spite of their very distinct formulation, I will illustrate that their exact quantum amplitudes show a strong resemblence in terms of the underlying representation theory. This observation can be appreciated upon formulating each of them in terms of a dilaton gravity model, suggesting a modified version of holography for the different models. Based largely on arXiv:2212.07696 and arXiv:2306.00941.
