The degree Kirchhoff index of graph $ G $ is defined as $ Kf^{*}(G) = \sum\limits_{{u, v}\subseteq V(G)}d(u)d(v)r_{G}(u, v) $, where $ d(u) $ is the degree of vertex $ u $ and $ r_{G}(u, v) $ is the resistance distance between the vertices $ u $ and

The Wiener index is one of the most classic and widely used indicators in topology. It reflects the average distance of any node pair in the graph. It not only makes the boundaries of given graphs clearer but also continuously generates topological i

Let $G$ be a simple connected graph of order $n$ with $m$ edges. The energy $\varepsilon(G)$ of $G$ is the sum of the absolute values of all eigenvalues of the adjacency matrix $A$. The Laplacian energy is defined as $LE(G)=\sum_{i=1}^{n}|\mu_{i}-

An n × n ray pattern A is called a spectrally arbitrary ray pattern if the complex matrices in Q(A) give rise to all possible complex polynomials of degree n.

To research the application and estimate performance in some small-scale vector sensor array by traditional direction of arrival estimate , we derivate the time delay expression of four small-scale non-uniform vector sensor array, the array direction
