Hypernetwork science via high-order hypergraph walks

WebA hypergraph is called 2-colorable if its vertices can be 2-colored so that every hyperedge (of size at least 2) contains at least one vertex of each color. An alternative term is Property B. A simple graph is bipartite iff it is 2-colorable. However, there are 2-colorable hypergraphs without Kőnig's property. WebFirst of all, we define the hypergraph, the homogeneous graph, and the heterogeneous graph of hypergraph. Table 2 lists some necessary mathematical notations used in this paper for illustrative purposes. Definition 1 Hypergraph. We denote the hypergraph by G = (V, E), where V denotes the set of M nodes and E denotes the set of N hyperedges. WebIn this paper, we determine the anti-Ramsey numbers of linear paths and loose paths in hypergraphs for sufficiently large n and give bounds for the anti-Ramsey numbers of Berge paths. Similar exact anti-Ramsey numbers are obtained for linear/loose cycles, and bounds are obtained for Berge cycles. field left covered by lots of sheets

WebSpecifically, we present a hypergraph parser to imitate guiding perception to learn intra-modal object-wise relationships. It parses the input modality into irregular hypergraphs to mine semantic clues and generate robust mono-modal representations. WebThis module implements generators of hypergraphs. All hypergraphs can be built through the hypergraphs object. For instance, to build a complete 3-uniform hypergraph on 5 points, one can do: sage: H = hypergraphs.CompleteUniform(5, 3) To enumerate hypergraphs with certain properties up to isomorphism, one can use method nauty (), which calls ...
