Convergence Theorems for Lattice Group-valued Measures explains limit and boundedness theorems for measures taking values in abstract structures. The book begins with a historical survey about these topics since the beginning of the last century, moving on to basic notions and preliminaries on filters/ideals, lattice groups, measures and tools which are featured in the rest of this text. Readers will also find a survey on recent classical results about limit, boundedness and extension theorems for lattice group-valued measures followed by information about recent developments on these kinds of theorems and several results in the setting of filter/ideal convergence. In addition, each chapter has a general description of the topics and an appendix on random variables, concepts and lattices is also provided. Thus readers will benefit from this book through an easy-to-read historical survey about all the problems on convergence and boundedness theorems, and the techniques and tools which are used to prove the main results. The book serves as a primer for undergraduate, postgraduate and Ph. D. students on mathematical lattice and topological groups and filters, and a treatise for expert researchers who aim to extend their knowledge base.


The eBook I am glad to read is a survey of the famous limit theorems for measures (Nikodým convergence theorem, Brooks-Jewett theorem, Vitali-Hahn-Saks theorem, Dieudonné convergence theorem, Schur convergence theorem). The first chapter seems to be the back bone of the eBook’s development. Not only it describes the development of the main theorems in the realm of convergence, but also provides a compact review of measures defined on algebras, vector latticevalued measures and measures defined on abstract structures. The use of these ideas is extensively described in Chapters 3 and 4. The historical development was enthusiastically approached since the second author was preparing his master’s thesis. Since then he worked consistently on the subject. Both authors are lovers of the historical development due to their Latin and Greek origin! Therefore the reader has the choice to appreciate an excellent piece of work on this area. The connection of Lattice Theory with Measure is explicitly described in this eBook and therefore the reader can also be addressed to Probability Theory. That is this eBook offers not only a strong background on limit theorems in Measure Theory, but also a solid theoretical insight into the Probability concepts. The norm of a measure, defined in Section 1.2, the definition of a measure on an algebra are essential tools to anybody working not only on Measure Theory but on Probability Theory as well. The next step, the definition of a measure defined on an abstract structure, needs more investigation in future work, while the authors cover completely the subject up to our days.

The definition of a Filter, defined firstly, and its dual notion of Ideal, defined later, are very nicely presented in Chapter 2. The relation between two Ideals is discussed in Section 2.1 as well as the Free Filters and P-Filters. These definitions and results are applied in Chapter 4. Being the authors consistent to their approach to limit theorems, they are extending Filters and Ideals with the corresponding limit theorems to Lattice Groups. Therefore a Lattice-Group-valued Measure is defined and the appropriate results are collected and presented. Nice examples on Filter Convergence in Lattice Groups help the reader to understand common ideas such as limsup or liminf through their development. The relation to Dedekind Complete Space is also discussed and related to Measure Theory. Therefore, I believe, the interested researcher has a compact, solid and rigorous presentation of Filters and Ideals.

The group with structure of lattice, known as (ℓ)-group, is what the authors investigate extensively in Chapter 3. The sense of Integration is very strictly presented under the light of Measure Theory. The convergence theorems for integrals are direct applications to Integration. The theoretical development of this Chapter is applied in Chapter 4, where a number of results is discussed under milder/weaker assumptions. Not only the limit theorems are presented but also interesting decomposition analogues for (ℓ)-group-valued measures are also discussed.

Chapter 4 is devoted to Filter (Ideal) Limit Theorems and their applications. Limit results and convergence theorems are presented in such a way the reader realizes that the authors are the grand masters of this subject. The Regularity of a Measure is discussed on any Dedekind Complete (ℓ)- Group. Topology is hidden everywhere and therefore also in Group-Valued Measures. This part is strongly related to the Preliminaries presented in Section 1.1, where the ideas of Topology, Measure and Banach Lattice are introduced.

The authors have collected more than 750 references on the subject. It is impressive not only for the extensively great number of references covering a wide variety of disciplines, but also for the fact that the authors refer to all of them inside the eBook.

I was glad when the authors asked me to write the preface. Then I realized that it was a hard work to go through this eBook. But I was eventually happy to realize that this excellent eBook covers the subject as well as possible. I did not have the chance to read such a compact review on the subject. I thank the authors for giving me the chance to read it.
