Math 603 COURSE INFORMATION - Spring 2014

Faculty: Ted Chinburg
Office Hours: By appointment
  1. (Basic Text 1) Lang, S.: "Algebra," third edition, Springer-Verlag, U.S.A. (2002), ISBN 038795385X.
  2. (Basic Text 2) Dummit, D.S. and Foote, M.: "Abstract algebra," third edition, Wiley, U.S.A., (2004), ISBN 0-471-43334-9.
  3. (Optional) Artin, M.: "Algebra," Prentice Hall, U.S.A., (1991) ISBN 0-13-004763-5.

Comments: The Dummit and Foote text provides a more compact but less complete presentation of the text than does Lang's book. Artin's book has a better discussion of matrix groups and of some other topics, such as groups defined by generators and relations. I will suggest readings from all three texts, as well as from some journal articles, for different parts of the course.
