Degree Sequences & Graph Isomorphism: GATE Havel-Hakimi
5+ day, 21+ hour ago (1330+ words) Use the Handshake Lemma and Havel-Hakimi mechanically, then learn why matching degree sequences cannot by themselves prove graph isomorphism. Exam prep & CS education Degree-sequence questions look like small counting exercises until the options force two different decisions. Can this sequence…...
DiNgHy offers null models for analyzing non-degenerate directed hypergraphs
6+ day, 23+ hour ago (81+ words) From epidemiological contact tracing to legislative politics, many of the networks that shape modern life cannot be faithfully described by simple pairwise links. A single event—an email sent to many recipients, a chemical reaction consuming several reagents and producing…...
Attributed hypergraphs capture structure and attributes realistically,
1+ week, 2+ day ago (61+ words) Group interactions are everywhere in the real world. Researchers co-author papers, shoppers buy products together, students hang out in clusters between classes, and users on question-and-answer platforms gather around the same posts. Scientists represent these many-to-many relationships using hypergraphs, mathematical…...
