Add both to Cart Add both to List. Triangular Form Contents xi 6. What gave me greater difficulty about the revision uerstein, perhaps, that which I have not added.

The subject matter chosen for discussion has been picked not only because it has become standard to present it at this level or because it is important in the whole general development but also with an eye to abstraacta “concreteness. True, one could develop the whole theory of dimension of a vector space as one of its corollaries, but, for the first time around, this seems like a much too fancy and unnatural approach to something so basic and down-to-earth.

In addition to the proof previously given for the existence, two other proofs of existence are carried out. In the chapter on groups I have largely expanded one section, that on Sylow’s theorem, and added two others, one on direct products and one on the structure of finite abelian groups.

One of the most telling proofs of the worth of an abstract vii viii Preface to the First Edition concept is what it, and the results about it, tells us in familiar situations.

Some are present merely heestein complete proofs in the text material, others to illustrate and to give practice in the results obtained. In almost every chapter an attempt is made to bring out the significance of the general results by applying them to particular problems. It was my desire to experiment by presenting to them material a little beyond that which is usually taught in algebra at the junior-senior level.

They are of varying degrees of difficulty.

I approached rev1smg Topics in Algebra with a certain amount of trepidation. Be that as it may, we shall concern ourselves with the introduction and development of some of the important algebraic systems-groups, rings, vector spaces, fields. After a great deal of thought and soulsearching, I decided not to do so.

A word about the problems. Abstrcta are routine and computational, many are very djfficult.

An algebraic system can be described as a set of objects together with some operations for combining them. Why is beyond me. Call and talk prescribed and referenced forms.

In point of fact, this decomposition was already in the first edition, at the end of the chapter on vector spaces, as a consequence of the structure of finitely generated abstacta over Euclidean rings.

However, the case of a finite group is of great importance by itself; the section on finite abelian groups underlines this importance. To mention just a few of these: It could be made to blend, but this would require a complete reworking of the material Preface to the Second Edition v of the book and a complete change in its philosophy-something I did not want to do.
