Avviso di Seminario

Il 12 settembre 2006 sara` inaugurata la serie di Colloquia Patavina:

Conferenziere: Joseph J. Kohn (Princeton University)
Titolo: Introduction to analysis on CR manifolds
Martedi 12 settembre, ore 16:00, aula 1A/150

I will give a historical account of the study of CR (Cauchy-Riemann) structures. I will discuss some relations with the theory of several complex variables and with partial differential equations. I will indicate how the analysis of CR structures involves techniques of microlocalization and multiplier ideals. The emphasis will be on on existence and regularity theorems which lead to the E. E. Levi problem in several complex variables and to Hans Lewy's example of a non-solvable PDE and its generalizations.

Biographical Sketch:
Joseph J. Kohn was born on May 18, 1932, in Prague. He received his B.A. from the Massachusetts Institute of Technology (1953) and his M.A. (1954) and Ph.D. (1956) from Princeton University. His thesis advisor was Donald C. Spencer.
Kohn was an instructor at Princeton University in 1956-57 before moving to Brandeis University, where he was on the faculty for ten years.
In 1968 he assumed his present position as a professor at Princeton University.
He has held visiting positions at the Courant Institute of Mathematical Sciences of New York University, the Institute for Advanced Study in Princeton, Harvard University, the Institut des Hautes tudes Scientifiques, Charles University of Prague, the University of Florence, the University of Buenos Aires, and the University of Mexico.
His many professional activities include serving on the AMS Board of Trustees (1972-82) and on the U.S. National Committee for Mathematics (2000-04).
Kohn is the recipient of a Sloan Fellowship and a Guggenheim Fellowship. He was elected a fellow of the American Academy of Arts and Sciences and a member of the U. S. National Academy of Sciences. In 1966 he was an invited speaker at the International Congress of Mathematicians. He was awarded the 1979 AMS Steele Prize for a Seminal Contribution to Research. He received an honorary doctorate from the University of Bologna and the Bolzano Medal of the Czechoslovak Mathematics and Physics Society in 1990. In 1993 he was awarded the First Order Prize of the Union of Czech Mathematicians and Physicists. In 2004 he was awarded the Stefan Bergman Prize. Established in 1988, the prize recognizes mathematical accomplishments in the areas of research in which Stefan Bergman worked. The Bergman Prize honors the memory of Stefan Bergman, best known for his research in several complex variables, as well as the Bergman projection and the Bergman kernel function that bear his name.
