Difference equations for correlation functions of $A^{(1)}_{n-1}$-face model with boundary reflection

Abstract

The $A^{(1)}_{n-1}$-face model with boundary reflection is considered on the basis of the boundary CTM bootstrap. We construct the fused boundary Boltzmann weights to determine the normalization factor. We derive difference equations of the quantum Knizhnik-Zamolodchikov type for correlation functions of the boundary model. The simplest difference equations are solved the in the case of the free boundary condition.
