\nAbstract:
\nTwo-dimensional Jackiw-Teitelboim (JT) gravity is a useful toy model<\/span><\/div>\n

to study various aspects of quantum gravity and holography. In a<\/span>
\nrecent paper by Saad, Shenker and Stanford, it was shown that JT<\/span>
\ngravity is holographically dual to a certain double-scaled matrix<\/span>
\nmodel. This is an example of the holography involving the ensemble<\/span>
\naverage, where the Hamiltonian of the boundary theory becomes the<\/span>
\nrandom matrix. This in particular implies that the correlator of two<\/span>
\npartition functions includes the contribution of spacetime wormhole<\/span>
\nconnecting the two asymptotic boundaries. In this talk I will give an<\/span>
\noverview of the recent developments of JT gravity matrix model.<\/span><\/p>\n<\/div>\n<\/div>\n

The colloquium will be held via ZOOM.<\/span><\/span><\/p>\n
