Discrepancy of random bipartite graphs (2)

This question is a modification of the one asked here, which turned out to ask for something too strong to be true. Given $k>0$ and a positive integer $n$, let $X, Y$ be two vertex sets of size $n$ ...

Discrepancy of random bipartite graphs

This is a crosspost from MathStackExchange (original question). Fix $k>0$ and let $X, Y$ be two vertex sets of size $n$ a positive integer (we're interested in the limit $n\to \infty$). Define a ...

Triangle coloring in random graph

Given $m$ persons (men and women) and $n$ balls, each person randomly selects $3$ balls. Once all of them complete the selection process, we color the balls with $2$ colors, white and black, such that ...

making a random uniform hypergraph linear

Let $\mathcal{H}_{n,p,h}=(V,E)$ be a random $h$-uniform hypergraph on $[n]$, sampled according to the usual binomial distribution. We known that with high probability, the number of edges in $\mathcal{...

Hyper-degree sequences: How to count them and how to construct hyper-graphs from them?

From an answer to this question I have learned how to ask this question properly. Consider a $k$-uniform hypergraph on $n$ nodes, i.e. a family of $k$-subsets of $[n]= \{1,2,\dots,n\}$ (the hyperedges)...

small hyperworlds ?

The theory of random graphs, after the pioneering classic work of Erdős & Rényi, has come to prominence with many further refinements, most notably the small world theory (Barabási, Watts, etc). ...

matchings in hypergraphs

I have been reading Pippenger and Spencer's paper "Asymptotic behavior of the chromatic index for hypergraphs" and they comment that their result is applicable to the family of random k-uniform ...

Small Configurations in Random Hypergraphs

I have a somewhat technical question regarding the distribution of small hypergraphs in randomly chosen hypergraphs. (My hope is that this is something that can be done using standard ideas about ...
