本文研究了幂零表代数的一个有趣的性质.利用表代数的Jordan-Holder型定理,证明了表代数满足幂零被幂零扩张仍是幂零的.但有限幂零群没有这样的扩张.
In this paper, we study an interesting property of nilpotent table algebra. By using Jordan-HOlder type theorem of table algebras, we prove that table algebras satisfying nilpotent extension condition are nilpotent, which does not correspond to extension problems of nilpotent groups exactly.
