ABSTRACT. We consider the six-vertex model with domain wall boundary conditions.
We choose the inhomogeneities as solutions of the Bethe Ansatz equations.
The Bethe Ansatz equations have many solutions, so we can consider a wide
variety of inhomogeneities. For certain choices of the inhomogeneities we
study arrow correlation functions on the horizontal line going through the
centre. In particular we obtain a multiple integral representation for the
emptiness formation probability that generalizes the known formul\ae\ for
XXZ antiferromagnets.
