Decompositions of quasirandom hypergraphs into hypergraphs of bounded degree

Stefan Ehard, Felix Joos

We prove that any quasirandom uniform hypergraph can be approximately decomposed into any collection of bounded degree hypergraphs with almost as many edges. In fact, our resul…

Low Weight Perfect Matchings

Stefan Ehard, Elena Mohr, Dieter Rautenbach

Answering a question posed by Caro, Hansberg, Lauri, and Zarb, we show that for every positive integer and every function with $σ\left(E(K_{4n})\…

Biholes in balanced bipartite graphs

Stefan Ehard, Elena Mohr, Dieter Rautenbach

A bihole in a bipartite graph with partite sets and is an independent set in with . We prove lower bounds on the largest order of biholes i…

A short proof of the blow-up lemma for approximate decompositions

Stefan Ehard, Felix Joos

Kim, Kühn, Osthus and Tyomkyn (Trans. Amer. Math. Soc. 371 (2019), 4655--4742) greatly extended the well-known blow-up lemma of Komlós, Sárközy and Szemerédi by proving a `blow-up…

A rainbow blow-up lemma for almost optimally bounded edge-colourings

Stefan Ehard, Stefan Glock, Felix Joos

A subgraph of an edge-coloured graph is called rainbow if all its edges have different colours. We prove a rainbow version of the blow-up lemma of Komlós, Sárközy and Szemerédi tha…

Pseudorandom hypergraph matchings

Stefan Ehard, Stefan Glock, Felix Joos

A celebrated theorem of Pippenger states that any almost regular hypergraph with small codegrees has an almost perfect matching. We show that one can find such an almost perfect ma…
