"e;Mastering the contents of Hall's book will lead a student to the frontiers of group theory. He will be well equipped to read any recent literature and start original research himself in this field… This remarkable book undoubtedly will become a standard text on group theory."e; — Eugene Guth, American Scientist"e;This is a book which I wish I could put in the hands of every graduate student who has shown an interest in the elements of group theory. The first 10 chapters would give him an excellent foundation in group theory, and there would still remain 10 chapters for his delight."e; — Richard Hubert Bruck, American Mathematical MonthlyThis encyclopedic treatment of the current knowledge of group theory was widely praised upon its 1959 publication for its readability and accessibility. Today this volume remains useful as an unsurpassed resource for learning and reviewing the basics of a fundamental and ever-expanding area of modern mathematics. Suitable for advanced undergraduate mathematics majors and graduate students in math, the treatment is largely self-contained and offers numerous helpful exercises.
