Completeness of the Bethe Ansatz for an open $q$-boson system with integrable boundary interactions

J. F. van Diejen, E. Emsiz, I. N. Zurrián

We employ a discrete integral-reflection representation of the double affine Hecke algebra of type $C^{\vee }C$ at the critical level q=1, to endow the open finite $q$-boson system w…
