A linear bound on the Manickam-Miklos-Singhi Conjecture

Alexey Pokrovskiy

Suppose that we have a set of numbers x_1, ..., x_n which have nonnegative sum. How many subsets of k numbers from {x_1, ..., x_n} must have nonnegative sum? Manickam, Miklos, and…

The Ramsey number of the clique and the hypercube

Gonzalo Fiz Pontiveros, Simon Griffiths, Robert Morris +2

The Ramsey number r(K_s,Q_n) is the smallest positive integer N such that every red-blue colouring of the edges of the complete graph K_N on N vertices contains either a red n-dime…

Spanning embeddings of arrangeable graphs with sublinear bandwidth

Julia Böttcher, Anusch Taraz, Andreas Würfl

The Bandwidth Theorem of Böttcher, Schacht and Taraz [Mathematische Annalen 343 (1), 175-205] gives minimum degree conditions for the containment of spanning graphs H with small ba…

An Extension of the Blow-up Lemma to arrangeable graphs

Julia Böttcher, Yoshiharu Kohayakawa, Anusch Taraz +1

The Blow-up Lemma established by Komlós, Sárközy, and Szemerédi in 1997 is an important tool for the embedding of spanning subgraphs of bounded maximum degree. Here we prove severa…

Advantage in the discrete Voronoi game

Dániel Gerbner, Viola Mészáros, Dömötör Pálvölgyi +2

We study the discrete Voronoi game, where two players alternately claim vertices of a graph for t rounds. In the end, the remaining vertices are divided such that each player recei…

Tight Hamilton cycles in random hypergraphs

Peter Allen, Julia Böttcher, Yoshiharu Kohayakawa +1

We give an algorithmic proof for the existence of tight Hamilton cycles in a random r-uniform hypergraph with edge probability p=n^{-1+eps} for every eps>0. This partly answers a q…

Maximum planar subgraphs in dense graphs

Peter Allen, Jozef Skokan, Andreas Würfl

Kühn, Osthus and Taraz showed that for each γ>0 there exists C such that any n-vertex graph with minimum degree γn contains a planar subgraph with at least 2n-C edges. We find the…
