“…Outside of these special weights, the relevant orthogonal polynomials are not classical but may be analyzed asymptotically using the Riemann-Hilbert method. This approach has been employed by the current authors and their collaborators to obtain exact asymptotic formulas for the partition function of the six-vertex model with DWBC as well as partial domain wall boundary conditions (pDWBC) [3,4,5,6,1,2,7,8]. This paper continues that program, extending the asymptotic analysis of the DWBC partition function employed in previous works to a six-vertex model with DWBC which is further constrained by a rotational symmetry.…”
