It is not clear whether there is a function f(r) such that for any 2-colouring of the edges of this hypergraph there is a partition into f(r) monochromatic tight paths.

Then, an LO k-colouring of an r-uniform hypergraph H is the same as a homomorphism from H (viewed as an r-ary structure) to LOr k. Thus, the problem of ﬁnding an LO k-colouring of an r-uniform hypergraph that has an LO 2-colouring is the same as PCSP(LOr 2,LO r k).

"If all edges have the same cardinality k, the hypergraph is said to be uniform or k-uniform, or is called a k-hypergraph. A graph is just a 2-uniform hypergraph. The degree d(v) of a vertex v is the number of edges that contain it. H is k-regular if every vertex has degree k. The dual of a uniform hypergraph is regular … See more 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 … See more Many theorems and concepts involving graphs also hold for hypergraphs, in particular: • Matching in hypergraphs; • Vertex cover in hypergraphs (also … 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. In other words, there must be no … See more Let $${\displaystyle V=\{v_{1},v_{2},~\ldots ,~v_{n}\}}$$ and $${\displaystyle E=\{e_{1},e_{2},~\ldots ~e_{m}\}}$$. Every hypergraph has an 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 See more Although hypergraphs are more difficult to draw on paper than graphs, several researchers have studied methods for the visualization of hypergraphs. In one possible … 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.
