Boundary Conformal Field Theory and Ribbon Graphs: a tool for open/closed string dualities
arXiv:0705.2331 · doi:10.1088/1126-6708/2007/07/021
Abstract
We construct and fully characterize a scalar boundary conformal field theory on a triangulated Riemann surface. The results are analyzed from a string theory perspective as tools to deal with open/closed string dualities.
