几类图及其乘积作为框架图的刻画

Characterization of some classes of graphs and their products as frame graph

H. Najafi, F. Abdollahi

摘要:

对于内积空间$\mathcal{H}$中的每个有限框架$φ$,我们关联一个单图$G(φ)$,称为{ \it框架图},其中框架的向量作为顶点,并且如果$\langle f, g\rangle \neq 0$ [1],则顶点$f$和$g$之间存在边。本文研究了几类著名的图及其乘积的$G(φ)$的阶与$\mathcal{H}$的维数之间的关系。

英文摘要:

To each finite frame $φ$ in an inner product space $\mathcal{H}$ we associate a simple graph $G(φ)$, called {\it frame graph}, with the vectors of the frame as vertices and there is an edge between vertices $f$ and $g$ provided that $\langle f, g\rangle \neq 0$ [1]. In this paper the relation between the order of $G(φ)$ and the dimension of $\mathcal{H}$ is investigated for some well-known classes of graphs and their products.
