Bridging the gap between graphs and networks

Gerardo Iñiguez, Federico Battiston, Márton Karsai
2020 Communications Physics  
A more mathematical network science may clarify the role of randomness in modeling, hint at underlying laws of behavior, and predict yet unobserved complex networked phenomena in nature.  ...  With pioneering work on the evolution of random graphs, graph theory is often cited as the mathematical foundation of network science.  ...  Since then, however, graph theory and network science have taken separate directions, with little overlap in their research questions and academic communities.  ...
