Reflection quantum Knizhnik-Zamolodchikov equations and Bethe vectors    [PDF]

Nicolai Reshetikhin, Jasper Stokman, Bart Vlaar

Solutions to reflection quantum Knizhnik-Zamolodchikov equations are constructed as bilateral sums involving "off-shell" Bethe vectors in case when the reflection matrix is diagonal and only the 2-dimensional representation of $U_q(\hat{\frak{sl}(2)})$ is involved. We also consider their rational and classical degenerations.
