Math 540: Linear Algebra II

Course description: This course is a natural continuation of Math 341. It covers topics in linear algebra which are essential for higher level courses in algebra and analysis. Topics include linear transformations, duality. Diagonalization of linear transformations.The Cayley Hamilton Theorem. Minimal polynomials. The Jordan canonical form. Exponential function. Inner product spaces, orthonormal bases and Gram-Schmidt orthogonalization. Operators on inner product spaces. Self-adjoint, unitary and positive operators. spectral theorem. Singular value decomposition. Bilinear and quadratic forms. Norms, bounded linear operators, matrix norms. Basic multilinear algebra.

 

Possible alternatives: Math 443 or Math 513 for a more applied treatment of some of the covered topics.
