It starts with the basic concepts of set theory and topological spaces and ends with the beginning of functional analysis. During his time at Minnesota, he supervised 5 Ph. Separation properties are treated differently among the three texts. I have no preference for any one ordering over any other. This book presents point set topology not only as an end in itself, but as a related discipline to the proper understanding of various branches of analysis and geometry. Digital master created according to Benchmark for Faithful Digital Reproductions of Monographs and Serials, Version 1. Its remarkable depth contributes to its versatility as a classroom text, a guide for independent study, and a reference.

It starts with the basic concepts of set theory and topological spaces and ends with the beginning of functional analysis. He also wrote a manuscript entitled Lectures on Algebraic and Analytic Number Theory, which was printed by Jones Letter Service. But I have to confess that, probably because of its main difference from the other two â€” namely, smaller print and smaller vertical spaces between lines â€” but perhaps also because the book contains precisely one diagram â€” I found Gaal less pleasurable to read and probably would not choose it as a text, were I to teach a course in topology. An understanding of topology is fundamental to the grasp of most branches of mathematical analysis and geometry. First, and more important, as far as I could find, there was no motivation for the defining, in the first place, of a topological space in terms of those familiar properties of open subsets.

Gaal solved it and with ErdĹ‘s jointly published the solution, giving him an ErdĹ‘s number of 1, which he re-earned in a subsequent two-part collaboration in 1955. Its remarkable depth contributes to its versatility as a classroom text, a guide for independent study, and a reference. Additional enrichment materials and advanced topic coverageâ€”including extensive material on differentiable manifolds, abstract harmonic analysis, and fixed point theoremsâ€”constitute an excellent reference for mathematics teachers, students, and professionals. Gaal's research interests included both number theory and analysis. A book that has been read but is in good condition.

This was, to me, the most salient feature of the book. Completions and compactifications end the book. Details: Master and use copy. This seems unusual to me, and part of me likes this idea, or at least understands how tempting this practice could be to an author. Of course I enjoyed it! He passed away on March 17, 2016, and is survived by his former wife Lisl also an emeritus faculty in the School of Mathematics , daughters Barbara and Dorothy, their husbands, and three grandchildren.

No question that I would recommend it. The answer is affirmative and depends on the development of the notion of an open set in a metric space. . NaĂŻve, but including the Axiom of Choice. Contents: Topological spaces -- Separation properties -- Compactness and uniformization -- Continuity -- Theory of convergence. Suitable for a complete course in topology, this text also functions as a self-contained treatment for independent study. The dust jacket for hard covers may not be included.

Digital Library Federation, December 2002.

I listened to Gaal's lectures with enthusiasm.

This wide-ranging treatment opens with basic concepts of set theory and topological spaces; it concludes with the rudiments of functional analysis.

Along this same line, definitions are too often not set off. These considerations are very likely minor, so ultimately, making a choice among the three is, to me, like making a choice in an Italian restaurant among spumoni, tortoni, and rum cake or, back to novels, in a Russian literature course, among Anna Karenina, War and Peace, and Crime and Punishment. In 1953, he became Instructor and then in 1954 Assistant Professor at Cornell University, and was a Research Associate at Yale University from 1958-60. Its comprehensive scope and coherent presentation make it equally valuable as a self-contained guide for those wishing to study at their own pace. The majority of pages are undamaged with minimal creasing or tearing, minimal pencil underlining of text, no highlighting of text, no writing in margins. Gaal went to Hungary to participate in the festivities where he gave a talk entitled When Is a Fibonacci Sequence Periodic? Suitable for advanced undergraduates and graduate students, this volume can serve as a text for a complete course in topology.

In fact, I found myself reading it the way, right or wrong, I sometimes read a novel though more slowly , for example turning ahead or opening it to an arbitrary page. Gaal retired in 1993 and subsequently moved to Nevada, where he spent the last years of his life. Very minimal damage to the cover including scuff marks, but no holes or tears. Steven Alexander Gaal was born as IstvĂˇn SĂˇndor GĂˇl on February 22, 1924, in Budapest, Hungary. The E-mail message field is required. I should note, though, that Kelley has, in addition, an Appendix which includes a fair amount of non-naĂŻve set theory.

I have two main criticisms. Its comprehensive scope and coherent presentation make it equally valuable as a self-contained guide for those wishing to study at their own pace. Also appearing are the Baire Category Theorem, the Principle of Uniform Boundedness and the Condensation of Singularities. Suitable for advanced undergraduates and graduate students, this volume can serve as a text for a complete course in topology. No question that this book is clear, concise, and in general worthy for its intended audience, namely advanced undergraduates and graduate students.
