Simion Stoilow

Simion Stoilow (born September 14, 1887 in Bucharest , † April 4, 1961 in Bucharest) was a Romanian mathematician .

Stoilow studied from 1907 at the Sorbonne in Paris , where he received his doctorate in 1916 with the dissertation " Sur une classe de fonctions de deux variables définies par les equations linéaires aux dérivées partielles " with Émile Picard . From 1919 to 1921 he was at the University of Alexandru Ioan Cuza Iași , then for two years at the University of Bucharest . Then he became a professor at the National Yuri Fedkovich University of Chernivtsi . From 1939 he was a professor in Bucharest, first at the Polytechnic University , from 1941 then at the University of Bucharest. There he was Rector from 1944 to 1946 and Dean of the Faculty of Mathematics and Physics from 1948 to 1951. From 1946 to 1948 he was the Romanian ambassador to France.

Stoilow was first deputy director and from 1954 director of the Mathematical Institute of the Romanian Academy, founded in 1949 . He held this position until his death. Today this institute is called the Simion Stoilow Institute of Mathematics of the Romanian Academy in his honor .

Stoilow gave lectures at the International Congress of Mathematicians (ICM) in Strasbourg in 1920 , in Bologna in 1928 and in Oslo in 1936 .

Stoilow made various contributions to mathematics, in particular to function theory . He is considered the father of the Romanian school in this field. The field of topological function theory was significantly co-founded by him. Stoilow's factorization theorem is named after him : Every continuous, open, discrete mapping between flat areas is the composition of a homeomorphism with a holomorphic function. The Stoilow- Kerékjártó - compaction is connected with his name.
