Title: Factorization & fundamental correlators in rational CFT with defect lines
Abstract: Conventional correlators in RCFT satisfy certain factorization properties. From these can be deduced a finite set of genus 0 world sheets whose correlators determine the full open/closed CFT. I will discuss how these factorization properties generalize when world sheets are allowed to contain topological defect lines. Additional properties then allows the identification of a set of fundamental world sheets, whose correlators determine the full open/closed CFT with defect lines.
