DESCRIPTION:In recent years\, it has become clear that the path integral o
f semiclassical 3D gravity offers a "coarse-grained" description of its ho
lographic 2D CFT. This relationship is particularly transparent when consi
dering the statistical moments of operator product expansion (OPE) coeffic
ients in the CFT. In this seminar\, I will explore the statistical propert
ies of OPE coefficients through the lens of typicality. I will introduce a
n ensemble of OPE data defined as the minimal solution to crossing consist
ent with approximate unitary invariance. Notably\, this ensemble is constr
ucted without relying on any specific matrix or tensor model. The ensemble
predicts new contributions to the sum over topologies in 3D gravity\, whi
ch are precisely realised by novel topologies in the bulk.\n\nhttps://indi
