Horst Schubert (mathematician)

Horst Schubert (born June 11, 1919 in Chemnitz ; † 2001 ) was a German mathematician .

Life and research

Schubert studied mathematics and physics at the universities of Frankfurt am Main , Zurich and Heidelberg , where he received his doctorate in 1948 under Herbert Seifert . Previously, even during the Second World War , he was in the rank of a lieutenant , cryptanalyst in the inspection 7 Group VI of the Army High Command (OKH / In 7 / VI). He then worked as an assistant in Heidelberg until 1956, where he completed his habilitation in 1952 . From 1959 he was associate professor and from 1962 full professor at Kiel University . From 1969 he was a professor at the University of Düsseldorf .

In 1949 he proved that nodes can be clearly decomposed into prime nodes . The classification of nodes with 2 bridges also goes back to him .

Theodor Bröcker is one of his doctoral students .

Together with the economist Rudolf Henn and the mathematician Hans Paul Künzi , Horst Schubert organized one of the first scientific conferences on operations research in Germany at the Mathematical Research Institute in Oberwolfach in 1969 .
