We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Lectures on elliptic partial differential equations (Pseudodifferential operator approach)
Alexander Komech
Abstract
Main goal of these lectures is a concise introduction to classical theory of elliptic partial differential equations. The lecture course was delivered at Mathematical Department of Vienna University in the fall of 2006.
We give detailed explanations of basic operations on distributions including the Fourier transform, the Sobolev spaces and embedding theorems, methods of pseudodifferential operators and their applications to obtain fundamental properties of elliptic partial differential equations: the Fredholm properties and smoothness of solutions.
This one-semester course is aimed at the third year students specialised in Mathematics, Physics and Engineering. We assume that the reader is familiar with the standard Calculus, the classical Fourier transform, and basic facts from the Hilbert space such as completeness of $L^2(R^n)$, and the Fredholm theory.
