Fundamentals of Modern Algebra

The purpose of this book is to provide a concise yet detailed account of fundamental concepts in modern algebra. The target audience for this book is first-year graduate students in mathematics, though the first two chapters are probably accessible to well-prepared undergraduates. The book covers a broad range of topics in modern algebra and includes chapters on groups, rings, modules, algebraic extension fields, and finite fields. Each chapter begins with an overview which provides a road map for the reader showing what material will be covered. At the end of each chapter we collect exercises which review and reinforce the material in the corresponding sections. These exercises range from straightforward applications of the material to problems designed to challenge the reader. We also include a list of "Questions for Further Study" which pose problems suitable for master's degree research projects.

Groups;Rings;Modules;Algebraic Extension Fields;Finite FieldsKey Features:A broad range of essential topics in modern algebra are included in a relatively short bookThe fundamental results on the structure of groups, namely the structure theorem for finitely generated abelian groups, Cauchy's Theorem and Sylow's Theorems are includedWe include a detailed discussion of localizations and absolute values and completions. There is a natural progression from modules over fields (vector spaces) to modules over Noetherian rings. We also include a thorough discussion of the discriminant which leads to a concise yet readable introduction to algebraic number theory
