A note on the generalized Gaussian Estrada index and Gaussian subgraph centrality of graphs

Let $ H $ be a simple, undirected, connected graph represented by its adjacency matrix $ \mathit{\boldsymbol{A}} $. For a vertex $ u \in V(H) $, the generalized Gaussian subgraph centrality of $ u $ in $ H $ is $ GSC (u, \beta) = \exp \left(- \beta \mathit{\boldsymbol{A}}^2 \right)_{uu} $, where $ \...
