Jirka Matoušek Prize Noon lecture: Extending partial automorphisms

Matěj Konečný

KAM

Abstract

A structure (e.g. graph or hypergraph) B is an EPPA-witness for a structure A if B contains A as an (induced) substructure and every isomorphism of induced substructures of A extends to an automorphism of B. We review some recent progress on this topic.
