Donald Erik Sarason (January 26, 1933 – April 8, 2017) was an American mathematician who made fundamental advances in the areas of Hardy space theory and VMO. He was one of the most popular doctoral advisors in the Mathematics Department at UC Berkeley. He supervised 39 Ph.D. theses at UC Berkeley.
Postdoc at the Institute for Advanced Study in 1963–1964, supported by a National Science Foundation Postdoctoral Fellowship. Then Sarason went to the University of California Berkeley as an Assistant Professor (1964–1967), Associate Professor (1967–1970) and until his retirement, Professor (1970–2012).
Sarason was awarded a Sloan Fellowship for 1969–1971.
Sarason was the author of 78 mathematics publications spanning the fifty years from 1963 to 2013. Sarason was the sole author on 56 of these publications; the other 22 publications were written with a total of 25 different co-authors.
The huge influence of Sarason’s publications on other mathematicians is reflected in unusually high citation rates. Google Scholar shows that Sarason’s publications have been cited over four-thousand times in the mathematical literature.
Sarason wrote an amazing total of 456 reviews for Mathematical Reviews/MathSciNet. These reviews were published from 1970 to 2009.
Teaching awards from UC Berkeley Mathematics Undergraduate Student Association, 2003 and 2006.
At various times, served on the editorial boards of Proceedings of the American Mathematical Society, Integral Equations and Operator Theory, and Journal of Functional Analysis.
Sarason reproved a theorem of G. Pick on when an interpolation problem can be solved by a holomorphic function that maps the disk to itself. Sarason’s approach not only gave a natural unification of the Pick interpolation problem with the Carathoédory interpolation problem (where the values of and its first derivatives at the origin are given), but it led to the Commutant Lifting theorem of Sz.-Nagy and Foiaş which inaugurated an operator theoretic approach to many problems in function theory.
