LECTURES: Monday, Wednesday, Friday 11:00am-12:00pm, in PSY B36.

DISCUSSION: Wednesday 10:00am-11:00am, in PSY B55. These will be used for going over lecture material and assignments in a way that is less structured than the lectures. Attendence of discussions is highly recommended.

INSTRUCTOR: Solesne Bourguin, office hours Monday 5:00pm-6:00pm, Wednesday 10:00am-11:00am. You can also email me (bourguin@math.bu.edu) to set up an appointment.

COURSE DESCRIPTION: Linear algebra is the study of vector spaces. The study of linear algebra begins with the determination of the solution set of a system of linear equations. This class focuses on abstract vector spaces, rather than on Euclidean space. Topics include: Linear transformations, characteristic polynomials, diagonalization and Jordan normal form, inner products, and spectral theory. The different parts of the class could be summarized as follows:

- Vector spaces: subspaces, linear combinations and systems of linear equations, linear dependence and independence, bases and dimension, maximal linearly independent subsets.
- Linear transforations and matrices: null spaces, ranges, matrix representation of a linear transformation, composition and matrix multiplication, invertibility and isomorphisms, change of coordinates matrices, dual spaces.
- Elementary matrix operations: elementary matrices and operations, rank of a matrix and matrix inverses, systems of linear equations.
- Determinants: determinants of order two, determinants of order n, properties of determinants.
- Diagonalization: eigenvalues and eigenvectors, diagonalizability, matrix limits.
- Inner product spaces: inner products and norms, Gram-Schmidt orthogonalization process, orthogonal complements, adjoints of linear operators, normal and self-adjoint operators, unitary and orthogonal operators and their matrices.
- Canonical forms: Jordan canonical form I, Jordan canonical form II.

TEXTBOOK: Linear Algebra, by Friedberg, Insel, and Spence, 4th ed., Prentice Hall.

GRADING: problem sets (50%), midterm (15%) and a final exam (35%). Because emergencies sometimes arise, I will drop the lowest homework grade from your homework average.

HOMEWORK: Every Friday for the next Friday. Late homeworks will not be accepted at all.

SCHEDULE OF EXAMS: The midterm will be held on Wednesday, March 2nd from 11:00am to 11:50am and will cover all that has been done up to Friday, February 26th included. The final exam is scheduled for Wednesday, May 4th from 12:30pm to 2:30 pm.

PROBLEM SETS: The following table summarizes the homework assignments (to be found in the exercises sections of the textbook) and due dates.
