Course Objective

The focus of this course will be on abstract vector spaces, linear operators, canonical forms, inner product spaces and bilinear forms. Students will be expected to learn the important theorems of linear algebra and understand their proofs.

Learning Outcomes of the Course Unit

1   be able to identify and use eigenvalues and related eigenvectors, and the characteristic and minimal polynomials of a linear operator.
2   be able to use diagonalizability, the Spectral Theorem for symmetric matrices over real numbers and its application to symmetric bilinear forms, quadratic forms, conic sections, quadric surfaces.
3   be able to use linear transformations and their matrix representations in bases interchangeably via the Change-of-Basis formula, and linear functionals, dual spaces.
4   be able to find complex eigenvalues and some canonical forms like the Jordan canonical form.
5   be able to use inner product spaces over real or complex numbers, Gram-Schmidt Orthogonalization Process to obtain orthogonal and orthonormal bases for subspaces, orthogonal complements and the orthogonal projection map onto a finite-dimensional subspace.
6   be able to use the adjoint of a linear operator, self-adjoint (=Hermitian), unitary, orthogonal and normal operators and matrices and the Spectral Theorem for normal operators in inner product spaces over real and complex numbers.
