Abstract Algebra: Review Problems on Groups and Galois Theory (Supplement to: Abstract Algebra, Second Edition by John A. Beachy and William D. Blair)

Introduction

Welcome to the essential companion for any serious student or scholar of abstract algebra. 'Abstract Algebra: Review Problems on Groups and Galois Theory' is an indispensable supplement to the acclaimed 'Abstract Algebra, Second Edition', authored by John A. Beachy and William D. Blair. This book aims to reinforce concepts and enhance understanding through comprehensive problem sets specifically focused on groups and Galois theory.

Detailed Summary of the Book

In this supplemental volume, you will delve into advanced mathematical concepts with a focus on two fundamental areas of abstract algebra: groups and Galois theory. These topics are central to algebraic structures and extend into various theoretical and practical applications across mathematics. This book contains expertly curated problems designed to test and deepen your understanding of these critical aspects.

The section on groups provides a thorough exploration of group theory, addressing topics such as group definitions, subgroup criteria, homomorphisms, and classification of groups. With a hands-on approach, the problems enable learners to appreciate the structural beauty and logic inherent in group theory.

Galois theory, the capstone of this book, covers the elegant correlation between field theory and group theory. Problems in this section guide you through Galois field extensions, solvability of polynomials by radicals, and the groundbreaking implications of Galois' fundamental theorem.
