| 释义 |
In network theory, the Braunstein-Ghosh-Severini entropy[1][2] (BGS entropy) of a network is the von Neumann entropy of a density matrix given by a normalized Laplacian matrix of the network. This definition of entropy does not have a clear thermodynamical interpretation. The BGS entropy has been used in the context of quantum gravity.[3] Notes and references1. ^Samuel L.
