Two author-paper networks and their coauthorship graph. Letters denote authors and numbers denote paper titles. These networks may be structured as hypergraphs on vertices A, B, C with hyperedges \(e_{1}=e_{2}=\{A,B,C\}\) for the rightmost network, and hyperedges \(e_{1}=e_{4}=\{A,B\}\), \(e_{2}=e_{5}=\{B,C\}\), \(e_{3}=e_{6}=\{A,C\}\) for the leftmost
