On generalizations of separating and splitting families
Daniel Condon, Samuel Coskey, Luke Serafin +1
The work in this article is concerned with two different types of families of finite sets: separating families and splitting families (they are also called "systems"). These famili…
The classification problem for finitely generated operator systems and spaces
Martín Argerami, Samuel Coskey, Mehrdad Kalantar +3
The classification of separable operator spaces and systems is commonly believed to be intractable. We analyze this belief from the point of view of Borel complexity theory. On one…
The conjugacy problem for automorphism groups of countable homogeneous structures
Samuel Coskey, Paul Ellis
We consider the conjugacy problem for the automorphism groups of a number of countable homogeneous structures. In each case we find the precise complexity of the conjugacy relation…
A López-Escobar theorem for metric structures, and the topological Vaught conjecture
Samuel Coskey, Martino Lupini
We show that a version of López-Escobar's theorem holds in the setting of logic for metric structures. More precisely, let denote the Urysohn sphere and let $\mathrm{M…
