Marcel Schützenberger
Marcel-Paul Schützenberger , also Marco Schützenberger, (born October 24, 1920 in Paris ; † July 29, 1996 there ) was a French mathematician .
Schützenberger's family came from Alsace , but went to France after the Franco-Prussian War of 1870/71. The chemist Paul Schützenberger was one of his ancestors . Schützenberger studied medicine and mathematics in Paris. In 1943 he made his first mathematical publication on Dedekind rings . From 1943 until the liberation of Paris in 1944 he was part of the Forces françaises libres of Charles de Gaulle .
After the war he continued his medical studies and received his doctorate in medicine in 1948. At the same time he continued his mathematical publications, e.g. B. on statistics, which he also used in his research in medicine. From 1948 to 1953 he was at the National Institute of Hygiene, where he was part of the team that discovered the trisomy . In 1953 he received his doctorate in mathematics in Paris with a thesis on the communication theory by Claude Shannon . He did research for the CNRS from 1953 and worked in the electronics laboratory at the Massachusetts Institute of Technology in 1956 , where Shannon was visiting professor in 1956/57. 1957 to 1963 he was a professor at the University of Poitiers and 1961/62 lecturer in the medical faculty of Harvard University . In 1963 he became research director of the CNRS and in 1964 professor at the Sorbonne . In 1970 he moved to the University of Paris VII (Denis Diderot), where he stayed for the rest of his career.
Schützenberger published on many mathematical areas, for example in combinatorics (such as Young Tableau ), algebra (semigroups, associations, etc.), computer science (including automata theory) and statistics. In algebraic combinatorics he published a lot with Alain Lascoux .
The Chomsky-Schützenberger theorem (1963, also named after Noam Chomsky ) states that every context-free language corresponds to a simple Dyck language .
Together with his friend David Berlinski , Schützenberger developed a mathematical critique of the Darwinian theory of evolution, according to which speciation through random mutations takes far more time than is available.
Schützenberger was a member of the French Académie des Sciences (since 1988) and the American Academy of Arts and Sciences (since 1993) and has received numerous other awards.
He and a group of his students published under the pseudonym M. Lothaire (including Applied Combinatorics on Words , Cambridge University Press 2005).
