Boundary conditions in Toda theories and minimal models

Understand

We show that the disc bulk one-point functions in a sl(n) Toda conformal field theory have a well-defined limit for the central charge c=n-1, and that their limiting values can be obtained from a limit of bulk one-point functions in the W_n minimal models.

• This comparison leads to a proposal for one-point functions for twisted boundary conditions in Toda theory.
