Course Description

 

 

The second term of Ma 5 will cover rings and modules. These topics are found in Dummit and Foote, parts II and III. Not all the material in the chapters will be covered. In addition, there will be supplemental material pulled from other textbooks that the students will be responsible for.

 

Policies

 

 

Grading: There will be a Midterm and a Final examination; each will be a timed (3 hour) take-home exam. The homework will count towards 40% of the final grade, while the midterm and Final will each count towards 30%.

Homework Policy: The solutions for the homework problems must be turned in every Tuesday by 4 PM in the marked box outside room 253 Sloan. Under regular circumstances, each students will be granted only one extension on homework, but arrangements have to be made in advanced with the instructor.

Students may, and are encouraged to, collaborate together on homework as long as each student writes up solutions individually in his or her own words. In solving homework problems, you should quote theorems and lemmas from class and the text. Results from the text in sections not yet covered or from other texts will not receive credit unless the proof is supplied.

Students may always cite results proved in class or earlier in the book, or results from previously assigned problems. If the problem refers to another problem in the book, students may use results from the referred to problem, unless otherwise indicated. Any other results must be proven to be used on homeworks or exams.
