Jackiw-Teitelboim supergravity, minimal strings, and matrix models

The author studies a family of two-dimensional Jackiw--Teitelboim (JT) supergravites, and, by using string theory techniques, he gives them complete definition to all orders in the topological expansion. This construction provides non--perturbative formulation for JT supergravity that is well--defined and stable. Furthermore, combination analytical numerical methods, shows explicitly how physics can be extracted gravity within this framework.
