Extension property for partial automorphisms of the $n$-partite and semigeneric tournaments
E-mail:

Submission date: 22 January 2024

Abstract:

We present a proof of the extension property for partial automorphisms (EPPA) for classes of finite n-partite tournaments for n ∈ {2,3, ... ,ω}, and for the class of finite semigeneric tournaments. We also prove that the generic ω-partite tournament and the generic semigeneric tournament have ample generics.
