Albert Nijenhuis

Albert Nijenhuis ( born November 21, 1926 in Eindhoven ) is a Dutch- American mathematician.

Nijenhuis 1952 by Jan Arnoldus Schouten his doctorate at the University of Amsterdam ( Theory of the geometric object) and was subsequently 1952/53, at Princeton University, and from 1953 to 1955 at the Institute for Advanced Study ( and again in 1961/62 when he was Guggenheim Fellow ). 1955/56, he was instructor at the University of Chicago. In 1956 he became an assistant professor and later professor at the University of Washington. In 1963 he became a professor at the University of Pennsylvania, where he retired in 1987. He has been a visiting professor at the University of Geneva (1967 /68), Dartmouth College (1977 /78) and 1964/64 Fulbright Lecturer at the University of Amsterdam.

Nijenhuis dealt with combinatorics including algorithms, global and local differential geometry and the theory of deformations in algebra and geometry. Different Lie - algebraic structures are named after him ( Frölicher - Nijenhuis bracket, Nijenhuis -Richardson bracket, Schouten - Nijenhuis bracket ).

In 1958 he was invited speaker at the International Congress of Mathematicians in Edinburgh (Geometric aspects of formal differential operations on tensor fields ).

He has been married since 1955 and has four children. Nijenhuis has the American citizenship. He is a corresponding member of the Royal Netherlands Academy of Sciences and a Fellow of the American Mathematical Society.
