The Borel complexity of non-Archimedean operator ranges
Martino Lupini
We completely classify the possible complexity classes of non-closed operator ranges on separable Banach spaces over a Polish non-Archimedean non-trivially valued field. These are…

Dilation theory in finite dimensions and matrix convexity
Michael Hartz, Martino Lupini
We establish a finite-dimensional version of the Arveson-Stinespring dilation theorem for unital completely positive maps on operator systems. This result can be seen as a general…

Fraïssé limits in functional analysis
Martino Lupini
We provide a unified approach to Fra\"ıssé limits in functional analysis, including the Gurarij space, the Poulsen simplex, and their noncommutative analogs. We obtain in this gene…
