General Course Information
Textbook: Contemporary Abstract Algebra, 6th Edition, by Joseph Gallian.
The main topic of this course is group theory. We plan to cover most of chapters 0-11 of Gallian,
plus possibly some
other special topics if we have time.
There will be 2 in-class midterms on Wed. 10/18 and Wed. 11/8, and a final exam on Monday 12/4 from 8-11am.
No makeup exams will be given.
Homework assignments will be due weekly on Fridays.
The final grade will be determined as follows: Homework 25%, Midterms 25%, Final Exam 50%.
More detailed descriptions, including a tentative syllabus, may be found in the first day course
handout here: Course syllabus
