Algebra - Thomas W. Hungerford

. .

Résumé :
Algebra fulfills a definite need to provide a self-contained, one volume, graduate level algebra text that is readable by the average graduate student and flexible enough to accommodate a wide variety of instructors and course contents. It contains an unusually large number of illustrative exercises....
