Various types of such Ricci curvatures capture different aspects of network geometry. In the present work, we investigate Bakry\u2013\u00c9mery\u2013Ricci curvature, a notion of discrete Ricci curvature that has been studied much in geometry, but so far has not been applied to networks. We explore on standard classes of artificial networks as well as on selected empirical ones to what the statistics of that curvature are similar to or different from that of other curvatures, how it is correlated to other important network measures, and what it tells us about the underlying network. We observe that most vertices typically have negative curvature. Furthermore, the curvature distributions are different for different types of model networks. We observe a high positive correlation between Bakry\u2013\u00c9mery\u2013Ricci and both Forman\u2013Ricci and Ollivier\u2013Ricci curvature, and in particular with the augmented version of Forman\u2013Ricci curvature while comparing them for both model and real-world networks. We investigate the correlation of Bakry\u2013\u00c9mery\u2013Ricci curvature with degree, clustering coefficient and vertex centrality measures. Also, we investigate the importance of vertices with highly negative curvature values to maintain communication in the network. Additionally, for Forman\u2013Ricci, Augmented Forman\u2013Ricci and Ollivier\u2013Ricci curvature, we compare the robustness of the networks by comparing the sum of the incident edges and the minimum of the incident edges as vertex measures and find that the sum identifies vertices that are important for maintaining the connectivity of the network. The computational time for Bakry\u2013\u00c9mery\u2013Ricci curvature is shorter than that required for Ollivier\u2013Ricci curvature but higher than for Augmented Forman\u2013Ricci curvature. We therefore conclude that for empirical network analysis, the latter is the tool of choice.<\/jats:p>","DOI":"10.1093\/comnet\/cnae019","type":"journal-article","created":{"date-parts":[[2024,5,28]],"date-time":"2024-05-28T09:38:06Z","timestamp":1716889086000},"source":"Crossref","is-referenced-by-count":3,"title":["Bakry\u2013\u00c9mery\u2013Ricci curvature: an alternative network geometry measure in the expanding toolbox of graph Ricci curvatures"],"prefix":"10.1093","volume":"12","author":[{"given":"Madhumita","family":"Mondal","sequence":"first","affiliation":[{"name":"The Institute of Mathematical Sciences (IMSc) , Chennai 600113, , India"},{"name":"Tamil Nadu , Chennai 600113, , India"},{"name":"Homi Bhabha National Institute (HBNI) , Mumbai 400094, Maharashtra, India"},{"name":"Max Planck Institute for Mathematics in the Sciences , 04103 Leipzig, Saxony, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6796-9604","authenticated-orcid":false,"given":"Areejit","family":"Samal","sequence":"additional","affiliation":[{"name":"The Institute of Mathematical Sciences (IMSc) , Chennai 600113, , India"},{"name":"Tamil Nadu , Chennai 600113, , India"},{"name":"Homi Bhabha National Institute (HBNI) , Mumbai 400094, Maharashtra, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Florentin","family":"M\u00fcnch","sequence":"additional","affiliation":[{"name":"Max Planck Institute for Mathematics in the Sciences , 04103 Leipzig, Saxony, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00fcrgen","family":"Jost","sequence":"additional","affiliation":[{"name":"Max Planck Institute for Mathematics in the Sciences , 04103 Leipzig, Saxony, Germany"},{"name":"Center for Scalable Data Analytics and Artificial Intelligence, Leipzig University , 04109 Leipzig, Saxony, Germany"},{"name":"Santa Fe Institute for the Sciences of Complexity , Santa Fe , NM 87501, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2024,5,28]]},"reference":[{"key":"2024052809380129300_cnae019-B1","volume-title":"Network Science","author":"Barab\u00e1si","year":"2016"},{"key":"2024052809380129300_cnae019-B2","doi-asserted-by":"crossref","first-page":"1173","DOI":"10.1038\/nature04209","article-title":"Towards a proteome-scale map of the human protein\u2013protein interaction network","volume":"437","author":"Rual","year":"2005","journal-title":"Nature"},{"key":"2024052809380129300_cnae019-B3","first-page":"243","article-title":"Equilibrium traffic assignment on an aggregated highway network for sketch planning","volume":"13","author":"Eash","year":"1979","journal-title":"Transport.
