Stefan Bergman (5 May 1895 – 6 June 1977) was a Poland-born American mathematician whose primary work was in complex analysis. He is known for the kernel function he discovered in 1922 at University of Berlin. This function is now known as the Bergman kernel. Bergman taught for many years at Stanford University.[1]
Biography
Born in Częstochowa, Congress Poland, Russian Empire, to a German Jewish family,[2] Bergman received his Ph.D. at University of Berlin in 1921 for a dissertation on Fourier analysis. His advisor, Richard von Mises, had a strong influence on him, lasting for the rest of his career.[3] In 1933, Bergman was forced to leave his post at the Berlin University because he was a Jew. He fled first to Russia, where he stayed until 1939, and then to Paris. In 1939, he emigrated to the United States, where he would remain for the rest of life.[3] He was elected a Fellow of the American Academy of Arts and Sciences in 1951.[4] He was a professor at Stanford University from 1952 until his retirement in 1972.[5] He was an invited speaker at the International Congress of Mathematicians in 1950 in Cambridge, Massachusetts[6] and in 1962 in Stockholm (On meromorphic functions of several complex variables).[7] He died in Palo Alto, California, aged 82.
Bergman Prize
The Stefan Bergman Prize in mathematics was initiated by Bergman's wife in her will, in memory of her husband's work. The American Mathematical Society supports the prize and selects the committee of judges.[8] The prize is awarded for:[8]
- the theory of the kernel function and its applications in real and complex analysis; or
- function-theoretic methods in the theory of partial differential equations of elliptic type with a special attention to Bergman's and related operator methods.
