Extremely amenable automorphism groups of countable structures
Mahmood Etedadialiabadi, Su Gao, Feng Li +1
In this paper we address the question: How many pairwise non-isomorphic extremely amenable groups are there which are separable metrizable or even Polish? We show that there are co…
Dense locally finite subgroups of Automorphism Groups of Ultraextensive Spaces
Mahmood Etedadialiabadi, Su Gao, François Le Maître +1
We verify a conjecture of Vershik by showing that Hall's universal countable locally finite group can be embedded as a dense subgroup in the isometry group of the Urysohn space and…
On Extensions of Partial Isomorphisms
Mahmood Etedadialiabadi, Su Gao
In this paper we study a notion of HL-extension (HL standing for Herwig--Lascar) for a structure in a finite relational language . We give a description of all finite…
On extensions of partial isometries
Mahmood Etedadialiabadi, Su Gao
In this paper we define a notion of S-extension for a metric space and study minimality and coherence of S-extensions. We show that every S-extension can be identified with an alge…
