Universality for transversal Hamilton cycles in random graphs

Micha Christoph, Anders Martinsson, Aleksa Milojević

A tuple of graphs on the same vertex set of size is said to be Hamilton-universal if for every map there exists a Hamilton cycle whose -th e…

Triangle-free -degenerate graphs have small fractional chromatic number

Anders Martinsson

A well-known conjecture by Harris states that any triangle-free -degenerate graph has fractional chromatic number at most . This conjecture has ga…

Local Shearer bound

Anders Martinsson, Raphael Steiner

We prove the following local strengthening of Shearer's classic bound on the independence number of triangle-free graphs: For every triangle-free graph there exists a probabili…

Improved bounds for zero-sum cycles in

Micha Christoph, Charlotte Knierim, Anders Martinsson +1

For a finite Abelian group , let denote the smallest positive integer such that for each labelling of the arcs of the complete digraph of order using elements…

Resolution of the Kohayakawa-Kreuter conjecture

Micha Christoph, Anders Martinsson, Raphael Steiner +1

A graph is said to be Ramsey for a tuple of graphs if every -coloring of the edges of contains a monochromatic copy of in color , for some …

Vertex-critical graphs far from edge-criticality

Anders Martinsson, Raphael Steiner

Let be any positive integer. We prove that for every sufficiently large there exists a -chromatic vertex-critical graph such that for every set $R \subset…
