The Bethe Equation at q=0, The M"obius Inversion Formula, and Weight Multiplicities: III. The X^{(r)}_N case
A. Kuniba, T. Nakanishi, Z. Tsuboi
It is shown that the numbers of off-diagonal solutions to the U_q(X^{(r)}_N) Bethe equation at q=0 coincide with the coefficients in the recently introduced canonical power series…

Bethe Equation at q=0, Möbius Inversion Formula, and Weight Multiplicities: I. sl(2) case
Atsuo Kuniba, Tomoki Nakanishi
The U_q(\hat{sl}(2)) Bethe equation is studied at q=0. A linear congruence equation is proposed related to the string solutions. The number of its off-diagonal solutions is express…
