与图相关的发展代数导子空间的特征定理

Characterization theorems for the spaces of derivations of evolution algebras associated to graphs

Paula Cadavid, Mary Luz Rodiño Montoya, Pablo M. Rodriguez

摘要:

已知具有非奇异矩阵的$n$维发展代数的导子空间为零。另一方面,具有秩为$n-1$的矩阵的发展代数的导子空间在文献中也得到了完整的描述。在这项工作中,我们提供了一个完整的描述空间的衍生物的演化代数相关的图形,根据图的孪生分区。对于没有至少有三个元素的孪生类的图,我们证明了相关的演化代数的导子空间为零。此外,我们描述了空间的导子的演化代数相关联的剩余家庭的有限图。值得指出的是,我们的分析包括有限维演化代数与任何秩的矩阵的例子。

英文摘要:

It is well-known that the space of derivations of $n$-dimensional evolution algebras with non-singular matrices is zero. On the other hand, the space of derivations of evolution algebras with matrices of rank $n-1$ has also been completely described in the literature. In this work we provide a complete description of the space of derivations of evolution algebras associated to graphs, depending on the twin partition of the graph. For graphs without twin classes with at least three elements we prove that the space of derivations of the associated evolution algebra is zero. Moreover, we describe the spaces of derivations for evolution algebras associated to the remaining families of finite graphs. It is worth pointing out that our analysis includes examples of finite dimensional evolution algebras with matrices of any rank.
