Cycles of distance-decreasing mappings in the ring of n-adic integers

V. I. Sushchanski, E. Moćko, V. V. Nekrashevych (2006)

Colloquium Mathematicae

We give a description of possible sets of cycle lengths for distance-decreasing maps and isometries of the ring of n-adic integers.

Images directes I : Espaces rigides analytiques et images directes

Jean-Yves Etesse (2012)

Journal de Théorie des Nombres de Bordeaux

Cet article est le premier d’une série de trois articles consacrés aux images directes d’isocristaux : ici nous considérons des isocristaux sans structure de Frobenius ; dans le deuxième [Et 6] (resp. le troisième [Et 7]), nous introduirons une structure de Frobenius dans le contexte convergent (resp. surconvergent).Pour un morphisme propre et lisse relevable nous établissons la surconvergence des images directes, grâce à un théorème de changement de base pour un morphisme propre entre espaces rigides...

Iterative differentiations in rings of unequal characteristic

Marilena Crupi, Gaetana Restuccia (2001)

Bollettino dell'Unione Matematica Italiana

Sia $R$ un anello di caratteristica diseguale. Si stabiliscono formule generali per gli endomorfismi di una differenziazione $F_{a}$ o $F_{c}$ -iterativa di $R$ , con $c$ non zerodivisore di R. Tali formule sono note nel caso della caratteristica eguale.

Orbit-cone correspondence for the proalgebraic completion of normal toric varieties

Genaro Hernandez-Mada, Humberto Abraham Martinez-Gil (2025)

Archivum Mathematicum

We prove that there is an orbit-cone correspondence for the proalgebraic completion of normal toric varieties, which is analogous to the classical orbit-cone correspondence for toric varieties.

Relations between localizations and $I$ -adic completions in commutative domains

Separable $ℵ_{k}$ -free modules with almost trivial dual

Daniel Herden, Héctor Gabriel Salazar Pedroza (2016)

Commentationes Mathematicae Universitatis Carolinae

An $R$ -module $M$ has an almost trivial dual if there are no epimorphisms from $M$ to the free $R$ -module of countable infinite rank $R^{(ω)}$ . For every natural number $k > 1$ , we construct arbitrarily large separable $ℵ_{k}$ -free $R$ -modules with almost trivial dual by means of Shelah’s Easy Black Box, which is a combinatorial principle provable in ZFC.
