Content summary

The course covers the theory of linear operators applied to matrix, differential, and integral equations. We also discuss Fredholdm integral equations and spectral theory.

Goals

This learning project aims to help applied mathematicians and engineers gain the understanding needed to read and critically assess papers that deal with functional analysis in its various forms.

We will talk about operator theory and linear operators as applied to functional analysis.
