My courses


I am a human being. I am a mathematician who speaks Swedish, Esperanto, English, and French. I am also a guest professor at Uppsala University.

The mathematicians who have meant most for me were Lars Hörmander (1931--2012) and André Martineau (1930--1972).

I have been the main scientific advisor of eighteen doctoral students from seven countries. They obtained their degrees during the period 1974--2016; four of these after my retirement. The last two from Stockholm University and l'Université des Sciences, des Techniques et des Technologies de Bamako.

In school I studied English, German, and French. My most inspiring teacher was Karl Axnäs (1899--1984). I started to study Russian at the age of 13. I have been more than one year in the United States and more than two years in France. I studied Persian (2007--2009) and Classical Greek (2010--2011) at Uppsala University and, during the academic year 2015/2016, Yiddish at Lund University. In July 2016 I participated in a seven-day course in Yiddish in Weimar.


I have done research on partial differential equations; then on complex analys and complex geometry, including geometry in infinitely many dimensions. My latest puplications on complex geometry (16-1) was published in March 2016. I have one paper on complex geometry submitted in September 2018 for possible publication.

Nowadays I am doing research on convexity and mostly on digital geometry, mathematical morphology, and discrete optimization---I am writing a book on these topics.

I am doing research also on Esperanto and Yiddish (publications 92-a, 08-a, 15-a, 15-b, 16-b). A manuscript was submitted in August 2018 for possible publication, and there are two longer texts in preparation.
