Course Description: Finite-dimensional vector spaces, linear maps, dual spaces, bilinear functions, inner products. Additional topics could include: canonical forms, multilinear algebra, numerical linear algebra (if time permits).
Prerequisites: C or higher in MAT 211 or 305 or 308 or AMS 210; C or higher in MAT 200 or MAT 250 or permission of instructor.
Attendance: Strongly encouraged, but not mandatory.
MAT 310 STARTS TOGETHER WITH MAT 315, AND WE SPLIT AFTER MIDTERM 1.
Major Topics Covered: Matrices and Operations on Matrices; Determinants of Matrices; Vector Spaces and Subspaces; Linear Transformations and Linear Operators; Kernels and Images; Basis for Vector Space and the Dimension of a Vector Space; Eigenvalues, Eigenvectors and the Diagonalization of Linear Operators; the Cayley-Hamilton Theorem; Inner Product Spaces; Self-adjoint Operators, Normal Operators, Orthogonal Operators; the Spectral Theorem.
Grading: Homework and quizzes each account for 10% of the total grade; each Midterm is worth 20%; the Final is worth 40%.
Letter grades are calculated as: A 100-95% A- 94-90% B+ 89-86% B 85-83% B- 82-79% C+ 78-75% C 74-71% C- 70-67% D+ 66-62% D 61-58% F<57%

Quiz: In addition to the homework, there will be 10 quizzes at the first 30 minutes of the recitations, scheduled on days after the homework deadlines above. In particular, the first quiz will be on Sep 1. The quizzes will test the knowledge from sections covered in the homework.
There are no make-ups for missed quizzes, for any reason. To account for possible exceptional absences and other circumstances, your lowest two scores from the homeworks will be dropped; i.e., your best 8/10 quizzes will be accounted for.
Any appeals about quizzes should be made in person with the TA, during their office hours or by appointment. Quizzes will be returned in the following recitation (or can be picked up during the TA's office hours).
Accessibility Support Center (SASC) Statement: If you have a physical, psychological, medical or learning disability that may impact your course work, please contact the Student Accessibility Support Center (SASC), ECC (Educational Communications Center) Building, room 128, (631) 632-6748. They will determine with you what accommodations, if any, are necessary and appropriate. All information and documentation is confidential.
Students who might require special evacuation procedures in the event of an emergency are urged to discuss their needs with both the instructor and DSS. For important related information, click here.
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 to follow their school-specific procedures. For more comprehensive information on academic integrity, including categories of academic dishonesty, please refer to the academic judiciary website at http://www.stonybrook.edu/commcms/academic_integrity/index.html.
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 behaviour 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.
AI policies:
Unless the instructor states otherwise, the use of AI tools is not allowed to obtain solutions to homework problems, other assignments, or tests. All work you submit should be your own, without any AI assistance. Any exceptions from this policy will be clearly specified by the course instructor.
If the course policy allows AI tools to be used for a particular project, such use must be disclosed in detail. (For example, you should write “Graphics for this presentation were created using ChatGPT”.) The final content of your work is your responsibility. Any mistakes or errors are reflected in your grade, even if they were introduced by AI tools. In particular, if AI tools suggest some references or citations, it is your responsibility to verify the accuracy of these references or citations.
