DESCRIPTION:In this talk I will present the computation of the partition f
unction of finite cut-off JT gravity (with positive\, zero or negative cur
vature) defined on a disk and coupled to conformal matter with central cha
rge c. The analysis is done in a regime where c is a large negative number
\, while the magnitude of the cosmological constant scales linearly with |
c| and the length of the boundary of the disk is kept finite. In this regi
me\, the gravitational path integral is dominated by a smooth geometry cor
responding to a saddle point of the action. By systematically taking into
account the quantum fluctuations about this saddle point\, one can obtain
a perturbative expansion of the partition function in powers of 1/|c|. I w
ill present the results for the leading and the first subleading terms in
this expansion.\n\nhttps://indico.cern.ch/event/1444880/
