摘要: We construct Laurent polynomial solutions of the boundary quantum Knizhnik--Zamolodchikov equation for $U_{q}(\widehat{\mathfrak{sl}}_{2})$ on parabolic Kazhdan--Lusztig bases. They are characterized by non-symmetric Koornwinder polynomials with specialized parameters. As a special case, we obtain solution minimal degree.
