Almost Self-Complementary 3-Uniform Hypergraphs
It is known that self-complementary 3-uniform hypergraphs on n vertices exist if and only if n is congruent to 0, 1 or 2 modulo 4. In this paper we define an almost self-complementary 3-uniform hypergraph on n vertices and prove that it exists if and ...

SYMMETRIC AND ASYMMETRIC RAMSEY PROPERTIES IN RANDOM HYPERGRAPHS
A celebrated result of Rödl and Ruciński states that for every graph $F$ , which is not a forest of stars and paths of length 3, and fixed number of colours

Shortest paths on polymatroids and hypergraphic polytopes [PDF]
Base polytopes of polymatroids, also known as generalized permutohedra, are polytopes whose edges are parallel to a vector of the form \(\mathbf{e}_i - \mathbf{e}_j\), where the \(\{\mathbf{e}_i\}_{i\in [n]}\) are the canonical basis vectors of \(\mathbb{

EIGENVALUES AND LINEAR QUASIRANDOM HYPERGRAPHS
Let $p(k)$ denote the partition function of $k$. For each $k\geqslant 2$, we describe a list of $p(k)-1$ quasirandom properties that a $k$-uniform hypergraph can have. Our work connects previous notions on linear hypergraph quasirandomness by Kohayakawa,

Finite Hypergraph Families with Rich Extremal Turán Constructions via Mixing Patterns
We prove that, for any finite set of minimal r-graph patterns, there is a finite family $\mathcal F$ of forbidden r-graphs such that the extremal Turán constructions for $\mathcal F$ are precisely the maximum r-graphs obtainable from mixing

Extremal, enumerative and probabilistic results on ordered hypergraph matchings
An ordered r-matching is an r-uniform hypergraph matching equipped with an ordering on its vertices. These objects can be viewed as natural generalisations of r-dimensional orders.
