摘要
A goal in 網絡 science is the geometrical characterization of complex 網絡s. In this direction, we have recently introduced Forman's discretization of Ricci curvature to the realm of undirected 網絡s. Investigation of this edge-centric 網絡 measure, Forman-Ricci curvature, in diverse model and real-world undirected 網絡s revealed that the curvature measure captures several aspects of the organization of undirected complex 網絡s. However, many important real-world 網絡s are inherently directed in nature, and the definition of the Forman-Ricci curvature for undirected 網絡s is unsuitable for the analysis of such directed 網絡s. Hence, we here extend the Forman-Ricci curvature for undirected 網絡s to the case of directed 網絡s. The simple 數學 formula for the Forman-Ricci curvature of a directed edge elegantly incor
