Identifying the borders of mathematical knowledge
Abstract Based on a divide and conquer approach, knBased on a divide and conquer approach, knowledge about nature has been organized into a set of interrelated facts, allowing a natural representation in terms of graphs: each `chunk' of knowledge corresponds to a node, while relationships between such chunks are expressed as edges. This organization becomes particularly clear in the case of mathematical theorems, with their intense cross-implications and relationships. We have derived a web of mathematical theorems from Wikipedia and, thanks to the powerful concept of entropy, identified its more central and frontier elements. Our results also suggest that the central nodes are the oldest theorems, while the frontier nodes are those recently added to the network. The network communities have also been identified, allowing further insights about the organization of this network, such as its highly modular structure.ork, such as its highly modular structure.

Conclusion The question of how knowledge is organizedThe question of how knowledge is organized represents a theme of broad interest, equally appealing to researchers from the most diverse areas as well as to lay people. In this paper, we set out to investigate how scientific knowledge, specifically mathematical theorems, is organized and interrelated. Thanks to Wikipedia, a comprehensive network of theorems has been compiled and investigated for the first time using complex networks. In particular, we identified the centrality of each theorem with respect to the whole network, which also paved the way to the identification of the frontier theorems—both classifications were possible because of the discriminative power of the diversity entropy, which is, for this network, correlated with the betweenness centrality. This approach is particularly interesting because it can provide insights about the development and organization of mathematical knowledge, as was confirmed by the strong negative correlation found between the diversity and the century of the theorem proof. According to our results, the oldest theorems tend to be the most important ones, in the sense that they have higher values of diversity entropy, in the average. On the other hand, the frontiers theorems are those recently added to the network. Additional structural information have been provided by the identification of the communities of theorems. It has been found that some of the most important mathematical theorems from different fields (e.g. Algebra, Calculus and Geometry) are tightly interconnected and tend to belong to the same community. As a future work, we intend to analyze Wikipedia in more depth, considering other scientific areas and respective relationships between them.and respective relationships between them.
