扭双指标代数的零关系Ringel对偶

On Ringel duality of dual extension algebras of posets

部分解决了惠昌常提出的一个公开问题,给出了广义V-型偏序集的对偶扩张代数的Ringel对偶代数的定义理想的生成元集,证明了该类代数仍是零关系代数.

One open question raised by Changchang Xi was partially solved. The Ringel dual algebras of dual extension algebra of generalized V-type posets were determined by giving their minimal generator-sets. It turns out that the Ringel dual algebras of this kind of pesets remain monomial.
