SUMMARY:Discrete Bulk Reconstruction
LOCATION:Zoom
DESCRIPTION:<p style="text-align: center;">The AdS/CFT correspondence posits a duality 
 between quantum theories of gravity in anti-de-Sitter (AdS) universes, and 
 conformal field theories (CFTs) defined on the boundaries of those universe
 s.&nbsp; In this talk, I'll explain how AdS/CFT works in a fully discrete s
 etting accessible even to a theoretical computer scientist like me.&nbsp; T
 he CFT side will encode the values of various min-cuts in a graph, and the 
 "bulk-boundary dictionary" will involve the computational problem of findin
 g a graph that has the prescribed cut values.&nbsp; Our main result is a na
 tural set of assumptions (a 1D boundary with data for contiguous subregions
 ) where this problem is not only always solvable, but is solvable via a pla
 nar graph that can be found in linear time.</p><p style="text-align: center
 ;">I'll present lots of open problems.This is work-in-progress, joint with 
 Jason Pollack.</p>
