 This book is strongly recommended to beginning graduate students who already have some background in abstract algebra, including elementary properties of groups, rings, and fields. The exposition and proofs are intended to present Galois theory as simply as possible. The large number of partially or fully solved examples is a special feature of the book. Reviews "This book is strongly recommended to beginning graduate students who already have some background in abstract algebra. The exposition and proofs are intended to present Galois theory in as simple a manner as possible ... The large number of partially or fully solved examples is its special feature."
