Álgebra Moderna - Joshep J. Rotman

Advanced Modern Algebra

Language: English

Book Description
This book's organizing principle is the interplay between groups and rings,
where “rings” includes the ideas of modules. It contains basic definitions,
complete and clear theorems (the first with briefsketches of proofs), and
gives attention to the topics of algebraic geometry, computers, homology,
and representations. More than merely a succession of definition-theorem-proofs,
this text put results and ideas in context so that students can appreciate why
a certain topic is being studied, and where definitions originate. Chapter
topics include groups; commutative rings; modules; principalideal domains;
algebras; cohomology and representations; and homological algebra. For
individuals interested in a self-study guide to learning advanced algebra and
its related topics.
