On the capacity of uniform hypergraphs

IEEE Transactions on Information Theory, 1990
The capacity of uniform hypergraphs can be defined as a natural generalization of the Shannon capacity of graphs. Corresponding to every uniform hypergraph there is a discrete memoryless channel in which the zero error capacity, in the case of the smallest list size for which it is positive, equals the capacity of the hypergraph, and vice versa.

Hardness of linearly ordered 4-colouring of 3-colourable 3-uniform hypergraphs

Symposium on Theoretical Aspects of Computer Science, 2023
A linearly ordered (LO) $k$-colouring of a hypergraph is a colouring of its vertices with colours $1, \dots, k$ such that each edge contains a unique maximal colour.

The Uniformity Lemma for hypergraphs

Graphs and Combinatorics, 1992
In 1973, E. Szemeredi proved a theorem which found numerous applications in extremal combinatorial problems--The Uniformity Lemma for Graphs. Here we consider an extension of Szemeredi's theorem tor-uniform hypergraphs.

Regularity method and large deviation principles for the Erdős–Rényi hypergraph

Duke mathematical journal, 2021
We develop a quantitative large deviations theory for random hypergraphs, which rests on tensor decomposition and counting lemmas under a novel family of cut-type norms. As our main application, we obtain sharp asymptotics for joint upper and lower tails

Transversals in Linear Uniform Hypergraphs

2020
This book gives the state-of-the-art on transversals in linear uniform hypergraphs. The notion of transversal is fundamental to hypergraph theory and has been studied extensively. Very few articles have discussed bounds on the transversal number for linear hypergraphs, even though these bounds are integral components in many applications.

Exact solution of the hypergraph Turán problem for k-uniform linear paths

Comb., 2011
A k-uniform linear path of length ℓ, denoted by ℙℓ(k), is a family of k-sets {F1,...,Fℓ such that |Fi ∩ Fi+1|=1 for each i and Fi ∩ Fbj = $\not 0$ whenever |i−j|>1.
