Some unpublished papers

Links and general references


This website exposes some of my unpublished papers (as pdf-files) and comments on some of my published articles. The left column contains links to the other sections of the site. Each section contains a short introduction to the area involved and links to the papers.

I imagine a great deal of the papers to be accessible to many people with an interest in mathematics but with little formal education. Some papers, however, also assume from the reader a certain basic knowledge of complex function theory.

I am interested in comments from readers, in particular concerning alternative (published or unpublished) proofs of my results. If some one finds errors in my papers, please let me be the first to hear about them.
