Abstract:

We will propose a relation between canonical purification of multipartite mixed state of CFT2 and hyperbolic string vertices of closed string field theory. Since bulk geometries of canonical purification share the same Riemann surfaces with the hyperbolic string vertices, we conjecture that the hyperbolic string vertices are foundamental building blocks of spacetime.
