The authors investigate properties of abelian convergence groups that contain a dense subgroup which is coarse. Cartesian products and minimality, Trans. Alla fine d’ogni capitolo riportiamo molti esercizi che riguardano il materiale esposto nel capitolo stesso.

On convergence groups with dense coarse subgroups by Dikran N Dikranjan 1 edition published in in English and held by 1 WorldCat member library worldwide A convergence group is a group endowed with a sequential convergence structure that is compatible with the group operations.

Conference papers and proceedings. Crediamo sia utile avere in un unico volume sia il testo sia gli esercizi con gli svolgimenti. Project Page Feedback Known Problems. This answers two questions posed by Dikranjan and Shakhmatov Proc.
As applications we give new proofs of the connection between the algebraic and the topological entropy in the abelian case and of the connection of the topological entropy with the finite depth for topological automorphisms. We prove arifmetica the positive answer to this question is equivalent to non-existence of measurable cardinals.
The material is illustrated with many examples and exercises, and open problems are formulated which should stimulate further research. As an application we answer the question posed in Pseudocompact sikranjan countably compact abelian groups: Most widely held works by Dikran N Dikranjan.
The problem of stability of these classes under the product, direct sum operations and taking subgroups or quotients is investigated.
Algebraic structure of small countably compact abelian groups by Dikran N Dikranjan 1 edition published in in English and held by 1 WorldCat dikrahjan library worldwide. Limit free computation of entropy by Dikran N Dikranjan 1 edition published in in English and held by 1 WorldCat member library worldwide Various limit-free formulas are given for the computation of the algebraic and the topological entropy, respectively in the settings of endomorphisms of locally finite discrete groups and of continuous endomorphisms of dikrwn disconnected compact groups.
We show that this growth can be either polynomial or exponential.
We also give a complete description of the structure of the transversable locally compact Abelian groups. We algebea that an infinite totally bounded topological group never admits a transversal group topology and we obtain a new criterion for precompactness in lattice-theoretical terms the existence of transversal group topologies for arltmetica large class of Abelian groups containing all divisible and all finitely generated groups.
All topological groups considered in this chapter algebrz assumed to be Hausdorff. Some examples are discussed. Knowledge of algebra, topology, and the basic notions of category theory is assumed. Categorical structure of closure operators with applications to topology, algebra, and discrete mathematics by Dikran N Dikranjan Book 15 editions published between and in English and held by WorldCat member libraries worldwide This book provides a comprehensive categorical theory of closure operators, with applications to topological and uniform spaces, groups, R-modules, fields and topological groups, as well as partially ordered sets and graphs.

The relationship between coarseness and completeness is investigated. This result is used to give conditions under which coarseness is preserved by products.
Abelian groups, module theory, and topology: This volume will be of interest to aritmeticca students and professional researchers in many branches of mathematics and theoretical computer science. AuthorEditorDedicateeHonoreeOther.
It is also proved that every Abelian group endowed with the finest totally bounded group topology has a closed generating suitable set. Continuous maps in the Bohr topology by Dikran N Dikranjan 1 edition published in in English and held by 1 WorldCat member library worldwide. In this case the description is obtained by means of a functorial correspondence, based on Pontryagin duality, between topological and linearly topologized groups introduced by Tonolo.
In particular, closure operators are used to give solutions to the epimorphism and co-well-poweredness problem in many concrete categories. Nei primi tre capitoli s’introducono i concetti alla base di ogni altro corso di matematica che possono coprire un corso bimestrale di Aritmetica. More generally, the Bohr topology of every locally compact Abelian group admits a suitable set.

Selected topics from the structure theory of topological groups by Dikran N Dikranjan 1 edition published in in English and held by 1 WorldCat member library worldwide This article contains open problems and questions covering the following topics: We show that totally minimal Abelian groups often have a suitable set.
The construction is delicate, as these subgroups sikranjan have non-trivial dijranjan sequences in some models of ZFC.
