摘要翻译：
采用频率矩展开法分析了Mott-Hubbard绝缘子中Luttinger和规则在半填充和大U$情况下的有效性，所述Mott-Hubbard绝缘子由广义Hubbard模型表示。对于缺少粒子-空穴对称性的三角形晶格上具有最近邻跳跃的Hubbard模型的特殊情况，结果揭示了和规则的严重违反。

英文摘要：
The frequency-moment expansion method is developed to analyze the validity of the Luttinger sum rule within the Mott-Hubbard insulator, as represented by the generalized Hubbard model at half filling and large $U$. For the particular case of the Hubbard model with nearest-neighbor hopping on a triangular lattice lacking the particle-hole symmetry results reveal substantial violation of the sum rule.
