A graph G is said to have bandwidth at most b, if there exists a labeling of the vertices by 1, 2, . . . , n, so that |i − j| ≤ b whenever {i, j} is an edge of G. Recently, Böttcher, Schacht, and Taraz verified a conjecture of Bollobás and Komlós which says that for every positive r,∆, γ, there exists β such that if H is an n-vertex r-chromatic graph with maximum degree at most ∆ which has band...

The Cl-free process starts with the empty graph on n vertices and adds edges chosen uniformly at random, one at a time, subject to the condition that no copy of Cl is created. For every l ≥ 4 we show that, with high probability as n → ∞, the maximum degree is O((n log n)), which confirms a conjecture of Bohman and Keevash and improves on bounds of Osthus and Taraz. Combined with previous result...

We prove that if G is a family of graphs with at most n vertices each, with constant degeneracy, with maximum degree at most O (n/ logn), and with total number of edges at most (1 − o(1)) (n 2 ) , then G packs into the complete graph Kn. This strengthens recent results of Böttcher Hladký Piguet Taraz, Messuti Rödl Schacht, Ferber Lee Mousset, Kim Kühn Osthus Tyomkyn, and Ferber Samotij related ...
