Abstract algebraThe book carefully develops the theory of different algebraic structures, beginning from basic definitions to some indepth results, using numerous examples and exercises throughout to aid the reader's understanding. This edition includes substantial new material in areas that include: tensor products, commutative rings, algebraic number theory and introductory algebraic geometry. Also, includes rings of algebraic integers, semidirect products and splitting of extensions, criteria for the solvability. of a quintic, and Dedekind Domains.
