On the eigenvalue and energy of extended adjacency matrix

Applied Mathematics and Computation, 2021
The extended adjacency matrix of graph G , A e x is a symmetric real matrix that if i ≠ j and u i u j ∈ E ( G ) , then the i j th entry is d u i 2 + d u j 2 / 2 d u i d u j , and zero otherwise, where d u indicates the degree of vertex u.

Attention adjacency matrix based graph convolutional networks for skeleton-based action recognition

Neurocomputing, 2021
Recent progress on human action recognition, fueled by the Graph Convolutional Network (GCN), has been substantial. However, two main problems are caused by the design strategy of graph convolution kernels: first, the partitioning strategy of neighbor ...

The generalized adjacency-distance matrix of connected graphs

Linear and multilinear algebra, 2023
Let G be a connected graph with adjacency matrix $ A(G) $ A(G) and distance matrix $ \mathcal {D}(G) $ D(G). The adjacency-distance matrix of G is defined as $ S(G) = \mathcal {D}(G) + A(G) $ S(G)=D(G)+A(G). In this paper, $ S(G) $ S(G) is generalized by
