This upper-level undergraduate textbook offers a latest view of algebra with a watch to new purposes that experience arisen lately. A rigorous creation to uncomplicated quantity idea, earrings, fields, polynomial idea, teams, algebraic geometry and elliptic curves prepares scholars for exploring their useful purposes relating to storing, securing, retrieving and speaking info within the digital international. it is going to function a textbook for an undergraduate direction in algebra with a robust emphasis on functions. The e-book deals a quick advent to straight forward quantity idea in addition to a reasonably whole dialogue of significant algebraic structures (such as earrings, fields, and teams) with a view in their use in bar coding, public key cryptosystems, error-correcting codes, counting strategies, and elliptic key cryptography. this can be the one access point textual content for algebraic structures that incorporates an in depth creation to elliptic curves, a subject matter that has leaped to prominence because of its significance within the resolution of Fermat's final Theorem and its incorporation into the swiftly increasing purposes of elliptic curve cryptography in shrewdpermanent playing cards. machine technology scholars will take pleasure in the powerful emphasis at the thought of polynomials, algebraic geometry and Groebner bases. the mix of a rigorous creation to summary algebra with an intensive assurance of its functions makes this booklet really targeted.
