An abstract approach in canonizing topological Ramsey spaces
Dimitris Vlitas
In \cite{To} S. Todorcevic introduced the notion of a topological Ramsey space and a list of axioms required to be satisfied by any such a space. Here we show that any topological…
Canonical equivalence relations on fronts on
Dimitris Vlitas
We prove that for every equivalence relation on a barrier on the space , for any , there exists so that the restr…
Canonical Borel equivalence relations on
Dimitris Vlitas
In this paper we complete the attempt of H. Lefmann to show that Borel equivalence relations on the -element subsets of , that respect an order type, have a finite Ramsey b…
A canonical partition theorem for uniform families of finite strong subtrees
Dimitris Vlitas
Extending a result of K. Milliken \cite{Mi2}, in this paper we prove a Ramsey classification result for equivalence relations defined on uniform families of finite strong subtrees…
An Infinite self dual Ramsey theorem
Dimitris Vlitas
In a recent paper \cite{So} S. Solecki proves a finite self dual Ramsey theorem that in a natural way gives simultaneously the classical finite Ramsey theorem \cite{Ra} and the Gra…
