摘要
本文研究了胞腔代数的直接构造问题.利用构造箭图并在其上添加关系的方法,获得了一种不可分解胞腔代数的构造方法'证明了总存在不可分解的胞腔代数A(对λ∈S(n))使得其卡当矩阵具有形如{n,1,…,1}的谱,从而拓广了胞腔代数的构造途径.
The problem on constructing cellular algebras is studied directly in this article. By quiver and relations,a method on constructing an indecomposable cellular is obtained.It is proved that there always exists an indecomposable cellular algebra A(λ∈S(n)) whose Cartan matrix has a spectrum like {n,1,…,1},which generalizes the ways to construct cellular algebras.
