EPPA for two-graphs and antipodal metric spaces
David Evans, Jan Hubička, Matěj Konečný +1
We prove that the class of finite two-graphs has the extension property for partial automorphisms (EPPA, or Hrushovski property), thereby answering a question of Macpherson. In oth…
Ramsey properties and extending partial automorphisms for classes of finite structures
David M. Evans, Jan Hubička, Jaroslav Nešetřil
We show that every free amalgamation class of finite structures with relations and (symmetric) partial functions is a Ramsey class when enriched by a free linear ordering of vertic…
Infinite primitive and distance transitive directed graphs of finite out-valency
Daniela Amato, David M. Evans
We give certain properties which are satisfied by the descendant set of a vertex in an infinite, primitive, distance transitive digraph of finite out-valency and provide a strong s…
Classification of some countable descendant-homogeneous digraphs
Daniela Amato, David M. Evans, John K. Truss
For finite q, we classify the countable, descendant-homogeneous digraphs in which the descendant set of any vertex is a q-valent tree. We also give conditions on a rooted digraph G…
