Abstract
Corrections to finite-size scaling are determined numerically for several levels of the three-state Potts quantum chain with various boundary conditions. It is found that the leading correction term behaves like N-0.8. In the case of periodic and twisted boundary conditions the coefficients of the N-0.8 term are determined by the three-point correlation functions of the conformal theory.Keywords
