DESCRIPTION:A wide class of two-dimensional gravitational models\, includi
 ng (2\,p) minimal strings and Jackiw-Teitelboim gravity\, are described by
  certain double-scaled matrix models. This allows for the study of non-per
 turbative effects in such theories\, via instanton calculus in the corresp
 onding matrix model dual. In matrix models\, non-perturbative contribution
 s to observables organize themselves in two distinct classes\, associated 
 to eigenvalue tunneling (corresponding to ZZ branes) and to determinant in
 sertions (corresponding to FZZT). We provide a recipe for systematically c
 omputing ZZ brane contributions in such models\, using a non-perturbative 
 formulation of the topological recursion. Also\, we show how the competing
  ZZ and FZZT brane effects show up in the Borel plane and in the large gen
 us asymptotics of several observables.
