Learning Objectives
Knowledge: method of separation of variables, methods of harmonic analysis, distributions, semigroup theory.
Skills: to analyze from the point of view of harmonic analysis a boundary-value problem for a partial differential equation in order to provide an explicit solution in terms of a suitable basis.
Skills acquired at the end of the course: to analyze an EDP-like problem both from a mathematical point of view and from a physical-applicative point of view.
