By studying the generating function of volumes of random hyperbolic surfaces with defects\, i.e. weighted geodesic boundaries\, we explore cri tical regimes where the surfaces develop macroscopic holes. We analyse the impact of this critical behavior on the density of states of the theory a t the boundary\, and we present a family of models that interpolate betwee n systems with $\\sqrt{E}$ and $E^{3/2}$\, which are commonly found in mod els of JT Gravity coupled to dynamical end-of-the-world and FZZT branes.\n \n(Waiting room will be used for all external participants. Best to show a real name in your Zoom ID to make the process easier.)\n LOCATION:https://researchseminars.org/talk/USC-HET/17/ END:VEVENT END:VCALENDAR
