Subhypergraph
WebLet K n be the complete graph on nvertices. Let C n be the ordinary cycle (graph) on n 3 vertices. If the vertices of C nare labelled consecutively as v 1;:::;v n;v 1, then we write C n= v 1:::v nv 1. For integer gwith 3 g n 1, let U n;g be the unicyclic graph on nvertices with girth g, obtained by adding an edge between one terminal vertex of the path P Web1 Feb 2024 · is Berge- F-free if it does not contain a subhypergraph which is Berge copy of F. This is a generalization of the usual, graph-based Berge hypergraphs, where F is a graph.

In mathematics, a hypergraph is a generalization of a graph in which an edge can join any number of vertices. In contrast, in an ordinary graph, an edge connects exactly two vertices. Formally, a directed hypergraph is a pair $${\displaystyle (X,E)}$$, where $${\displaystyle X}$$ is a set of elements called … See more Undirected hypergraphs are useful in modelling such things as satisfiability problems, databases, machine learning, and Steiner tree problems. They have been extensively used in machine learning tasks as the data model … See more Although hypergraphs are more difficult to draw on paper than graphs, several researchers have studied methods for the visualization of … See more Because hypergraph links can have any cardinality, there are several notions of the concept of a subgraph, called subhypergraphs, partial hypergraphs and section hypergraphs. Let $${\displaystyle H=(X,E)}$$ be the hypergraph … See more A parallel for the adjacency matrix of a hypergraph can be drawn from the adjacency matrix of a graph. In the case of a graph, the adjacency matrix is a square matrix which … See more Many theorems and concepts involving graphs also hold for hypergraphs, in particular: • See more Classic hypergraph coloring is assigning one of the colors from set $${\displaystyle \{1,2,3,...,\lambda \}}$$ to every vertex of a hypergraph in such a way that each hyperedge contains at least two vertices of distinct colors.
