An Improved Upper Bound on the Threshold Bias of the Oriented-cycle Game

Anita Liebenau, Abdallah Saffidine, Jeffrey Yang

We study the -biased Oriented-cycle game where two players, OMaker and OBreaker, take turns directing the edges of (the complete graph on vertices). In each round, OMa…

On multicolor Turán numbers

József Balogh, Anita Liebenau, Letícia Mattos +1

We address a problem which is a generalization of Turán-type problems recently introduced by Imolay, Karl, Nagy and Váli. Let be a fixed graph and let be the union of e…

Universality for graphs of bounded degeneracy

Peter Allen, Julia Böttcher, Anita Liebenau

Given a family of graphs, a graph is called -universal if contains every graph of as a subgraph. Following the extensive research o…

On the minimum degree of minimal Ramsey graphs for cliques versus cycles

Anurag Bishnoi, Simona Boyadzhiyska, Dennis Clemens +3

A graph is said to be -Ramsey for a -tuple of graphs , denoted by , if every -edge-coloring of contains a monochromatic c…

Asymmetric Ramsey Properties of Random Graphs for Cliques and Cycles

Anita Liebenau, Letícia Mattos, Walner Mendonça +1

We say that if, in every edge colouring , we can find either a -coloured copy of or a -coloured copy of . The well-known Kohayakawa-…

Asymptotic enumeration of hypergraphs by degree sequence

Nina Kamčev, Anita Liebenau, Nick Wormald

We prove an asymptotic formula for the number of -uniform hypergraphs with a given degree sequence, for a wide range of parameters. In particular, we find a formula that is asym…

Asymptotic enumeration of digraphs and bipartite graphs by degree sequence

Anita Liebenau, Nick Wormald

We provide asymptotic formulae for the numbers of bipartite graphs with given degree sequence, and of loopless digraphs with given in- and out-degree sequences, for a wide range of…

The threshold bias of the clique-factor game

Anita Liebenau, Rajko Nenadov

Let be an integer and consider the following game on the complete graph for : Two players, Maker and Breaker, alternately claim previously uncla…

Most binary matrices have no small defining set

Carly Bodkin, Anita Liebenau, Ian M. Wanless

Consider a matrix chosen uniformly at random from a class of matrices of zeros and ones with prescribed row and column sums. A partially filled matrix is a $\m…

The size Ramsey number of graphs with bounded treewidth

Nina Kamcev, Anita Liebenau, David R. Wood +1

A graph is Ramsey for a graph if every 2-colouring of the edges of contains a monochromatic copy of . We consider the following question: if has bounded treewidt…

An approximate version of Jackson's conjecture

Anita Liebenau, Yanitsa Pehova

In 1981 Jackson showed that the diregular bipartite tournament (a complete bipartite graph whose edges are oriented so that every vertex has the same in- and outdegree) contains a…

Caterpillars in Erdős-Hajnal

Anita Liebenau, Marcin Pilipczuk, Paul Seymour +1

Let be a tree such that all its vertices of degree more than two lie on one path, that is, is a caterpillar subdivision. We prove that there exists such that for ever…

Asymptotic enumeration of graphs by degree sequence, and the degree sequence of a random graph

Anita Liebenau, Nick Wormald

In this paper we relate a fundamental parameter of a random graph, its degree sequence, to a simple model of nearly independent binomial random variables. This confirms a conjectur…
