Abstract
摘要 |
In this talk, I will give a review of the mathematical foundation of the boundary-bulk (or open-closed) rational conformal field theories. In particular, we will discuss all the ingredients of an open-closed conformal field theory, including bulk fields OPE, boundary fields OPE, boundary conditions, modular invariance conditions, Cardy conditions, boundary states, etc. As a consequence, we obtain a precise mathematical description of open-closed rational conformal field theories. Using this precise mathematical language, one can formulate precisely and prove rigorously the so-called "boundary-bulk duality" (or open-closed duality). If time permits, I can also briefly mention how it leads to a complete classification of gapless edges of 2+1D topological orders. |
