Czesław Ryll-Nardzewski

Czesław Ryll-Nardzewski (born October 7, 1926 in Wilno , † September 18, 2015 in Breslau ) was a Polish mathematician .

Life

Czesław Ryll-Nardzewski achieved his university entrance qualification in secret school courses in Vilnius, which was occupied by Germany. After the end of the war he studied mathematics and physics at the Maria Curie Skłodowska University in Lublin , where he graduated in 1948. He then moved to the University of Breslau , where he completed his habilitation in 1951 and was appointed associate professor in 1954 and then full professor in 1964. From 1979 until his retirement in 1996 he taught at the Technical University of Wroclaw .

Ryll-Nardzewski had been a member of the Polish Academy of Sciences since 1967 . He was editor of the journal Probability and Mathematical Statistics and co-editor of Bulletin of the Polish Academy of Sciences , Colloquium Mathematicum , Fundamenta Mathematicae and Studia Mathematica .

In 1992, Ryll-Nardzewski was awarded the Stefan Banach Medal .

Ryll-Nardzewski's areas of work were functional analysis , fundamentals of mathematics , probability theory and measure theory . An essential contribution to basic research is Ryll-Nardzewski's theorem , according to which no finite axiomatization of Peano arithmetic is possible. His theorem on the characterization of -categorical theories is also called the Ryll-Nardzewski Theorem . Also, the fixed point omega-categorical theory in functional analysis bears his name. ${\displaystyle \omega }$
