  1. Coherent extension of partial automorphisms, free amalgamation and automorphism groups.Daoud Siniora & Sławomir Solecki - 2020 - Journal of Symbolic Logic 85 (1):199-223.
    We give strengthened versions of the Herwig–Lascar and Hodkinson–Otto extension theorems for partial automorphisms of finite structures. Such strengthenings yield several combinatorial and group-theoretic consequences for homogeneous structures. For instance, we establish a coherent form of the extension property for partial automorphisms for certain Fraïssé classes. We deduce from these results that the isometry group of the rational Urysohn space, the automorphism group of the Fraïssé limit of any Fraïssé class that is the class of all ${\cal F}$-free structures, and (...)

  • Bowtie‐free graphs and generic automorphisms.Daoud Siniora - 2023 - Mathematical Logic Quarterly 69 (2):221-230.
    We show that the countable universal ω‐categorical bowtie‐free graph admits generic automorphisms. Moreover, we show that this graph is not finitely homogenisable.
