Isometry groups of Polish ultrametric spaces
Riccardo Camerlo, Alberto Marcone, Luca Motto Ros
We solve a long-standing open problem, formulated by Krasner in the 1950's, in the context of Polish (i.e. separable complete) ultrametric spaces by providing a characterization of…
Reducibility by polynomial functions
Riccardo Camerlo, Carla Massaza
We study the preorder on the family of subsets of an algebraically closed field of characteristic defined by letting if there exists a polynomial such th…
Fences, their endpoints, and projective Fraïssé theory
Gianluca Basso, Riccardo Camerlo
We introduce a new class of compact metrizable spaces, which we call fences, and its subclass of smooth fences. We isolate two families of Hasse diagrams…
Polish metric spaces with fixed distance set
Riccardo Camerlo, Alberto Marcone, Luca Motto Ros
We study Polish spaces for which a set of possible distances is fixed in advance. We determine, depending on the properties of , the complexity of the…
Modal operators and toric ideals
Riccardo Camerlo, Giovanni Pistone, Fabio Rapallo
In the present paper we consider modal propositional logic and look for the constraints that are imposed to the propositions of the special type by the structure of the re…
Analytic sets of reals and the density function in the Cantor space
Alessandro Andretta, Riccardo Camerlo
We study the density function of measurable subsets of the Cantor space. Among other things, we identify a universal set for subsets of in ter…
