Bethe Equation at q=0, Möbius Inversion Formula, and Weight Multiplicities: I. sl(2) case
摘要：
研究了q=0时的U_q（\hat{sl}（2））Bethe方程.提出了一个与弦解有关的一次同余方程。它的非对角解的个数用一个显式的组合公式表示，并且与量子空间的权重数相一致。
英文摘要：
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 expressed in terms of an explicit combinatorial formula and coincides with the weight multiplicities of the quantum space.
