Big Ramsey degrees of 3-uniform hypergraphs

Martin Balko, David Chodounský, Jan Hubička +2

Given a countably infinite hypergraph $R$ and a finite hypergraph $A$ , the big Ramsey degree of $A$ in $R$ is the least number $L$ such that, fo…

Extending partial automorphisms of $n$ -partite tournaments

Jan Hubička, Colin Jahel, Matěj Konečný +1

We prove that for every $n \geq 2$ the class of all finite $n$ -partite tournaments (orientations of complete $n$ -partite graphs) has the extension property for partial automorphisms…

Density and Fractal Property of the Class of Oriented Trees

Jan Hubička, Jaroslav Nešetřil, Pablo Oviedo

We show the density theorem for the class of finite oriented trees ordered by the homomorphism order. We also show that every interval of oriented trees, in addition to be dense, i…
