MA552 is a graduate-level course in linear algebra. The major goal of this
course is to consider, from the general axiomatic point of view, basic ideas
of finite dimensional vector spaces. Also some advanced
topics—such as multilinear algebra, and normed, inner product, and topological
vector spaces—will be considered, provided that the mandatory material is covered.
It is assumed that students have already taken an undergraduate linear algebra course,
such as MA232. However, to assure that everyone is familiar with the undergraduate
material and to acclimate to the general axiomatic approach through intuitive examples,
this course will start with an extensive review of the elementary linear algebra topics:
geometrical vector theory, linear transformations in two- and three-dimensional Euclidean
spaces, real matrices, determinants, eigenvalues, and eigenvectors. This review will correspond
to the first 5 chapters of the Gilbert Strang's book and will also include a discussion
of important applications (in particular to systems of differential equations),
and should take up the first 4-5 lectures. The second part of the course will
be completely devoted to the formal axiomatic approach to finite-dimensional vector spaces.
