Christer Oscar Kiselman
Christer Oscar Kiselman is a human being.
Somewhat more precisely, he is a mathematician who speaks Swedish, Esperanto, English, and French.
He has done research on partial differential equations, then on complex analysis and complex geometry. Nowadays he works mainly on digital geometry, mathematical morphology, and discrete optimization.

I am a mathematician who speaks Swedish, Esperanto, English, and French. Since 2014, I am 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 lived 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 during many years 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. A later paper on complex geometry was accepted in March 2019 for publication.
Nowadays I am working mainly 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). I have two longer texts in preparation.
