Projective length, phantom extensions, and the structure of flat modules
Matteo Casarosa, Martino Lupini
We consider the natural generalization of the notion of the order of a phantom map from the topological setting to triangulated categories. When applied to the derived category of…
Complexity classes of Polishable subgroups
Martino Lupini
In this paper we further develop the theory of canonical approximations of Polishable subgroups of Polish groups, building on previous work of Solecki and Farah--Solecki. In partic…
Computable topological abelian groups
Martino Lupini, Alexander Melnikov, Andre Nies
We study the algorithmic content of Pontryagin - van Kampen duality. We prove that the dualization is computable in the important cases of compact and locally compact totally disco…
An invitation to model theory and C*-algebras
Martino Lupini
We present an introductory survey to first order logic for metric structures and its applications to C*-algebras.
