Kronecker表示的子表示

Subrepresentations of Kronecker representations

Yang Han

摘要:

矩阵束理论的一个挑战是找到一个Kronecker表示是另一个Kronecker表示的子因子的充分和必要条件。这个问题被减少到一个数值标准的克罗内克表示是另一个克罗内克表示的克罗内克不变量的子表示。问题的关键是多项式环上矩阵秩的计算。为此,引入了一种泛化和专业化的方法。这种方法是适用于提供一个数值准则的预投射(分别。正则的,预内射的)克罗内克表示是另一个预内射的子表示(或正则的,预内射的)Kronecker表示的Kronecker不变量。

英文摘要:

Translated into the language of representations of quivers, a challenge in matrix pencil theory is to find sufficient and necessary conditions for a Kronecker representation to be a subfactor of another Kronecker representation in terms of their Kronecker invariants. The problem is reduced to a numerical criterion for a Kronecker representation to be a subrepresentation of another Kronecker representation in terms of their Kronecker invariants. The key to the problem is the calculation of ranks of matrices over polynomial rings. For this, a generalization and specialization approach is introduced. This approach is applied to provide a numerical criterion for a preprojective (resp. regular, preinjective) Kronecker representation to be a subrepresentation of another preprojective (resp. regular, preinjective) Kronecker representation in terms of their Kronecker invariants.
