MAT 544  Algebra III: Homological algebra, representation theory and commutative algebra   Fall 2018 

TuTh 10-11:20am Math 4-130

Instructor: Ljudmila Kamenova
Office: Math Tower 3-115
Office hours: Wednesdays 1-3pm, MLC on Fridays 1-2pm

The course will introduce three components. First we will give an overview of commutative algebra. Next we will review homological algebra from MAT 535, Algebra II, and we will survey more advanced topics. Finally, we will outline the structure theory of finite dimensional complex representations of finite groups and of semisimple Lie algebras.

Syllabus:

1. Modules, Nakayama's lemma, Noetherian rings.

2. The Nullstellensatz and Spec A.

3. Rings of fractions and localization.

4. Primary decomposition.

5. DVRs and normal integral domains.

6. Chain complexes.

7. Derived functors.

8. Spectral sequences.

9. The Derived category.

10. Representations of finite groups.

11. Representations of symmetric groups.

12. Classification of semisimple Lie algebras.

13. The Weyl Character Formula.


Recommended books: There is no required textbook. The lectures will be based on the following references.


Grading: The final course grade will be determined based on class participation - 30%, homework sets - 40%, and a final oral report by each student - 30%.

Every student will give an oral in-class presentation of approximately 30 minutes in the last few weeks of the semester. The topic of the presentation is to be determined by the student and the instructor jointly. It may be on anything related to the course but not directly covered during lectures or on the problem sets, e.g., a skipped section of the textbooks, an interesting sequence of (unassigned) textbook problems, related material from another algebra textbook, etc. The topic should be discussed with the instructor and approved no later than November 1st.

Academic Integrity Statement. Each student must pursue his or her academic goals honestly and be personally accountable for all submitted work. Representing another person's work as your own is always wrong. Faculty are required to report any suspected instances of academic dishonesty to the Academic Judiciary. Faculty in the Health Sciences Center (School of Health Technology & Management, Nursing, Social Welfare, Dental Medicine) and School of Medicine are required tofollow their school-specific procedures. For more comprehensive information on academic integrity, including categories of academic dishonesty, please refer to the academic judiciary website.


Critical Incident Management Statement. Stony Brook University expects students to respect the rights, privileges, and property of other people. Faculty are required to report to the Office of Judicial Affairs any disruptive behavior that interrupts their ability to teach, compromises the safety of the learning environment, or inhibits students' ability to learn. Faculty in the HSC Schools and the School of Medicine are required to follow their school-specific procedures.
