Karp Prize Recipients
2008 Karp Prize
Zlil Sela, Hebrew University
The recipient of the 2008 Karp Prize is Zlil Sela for his fundamental work connecting logic with geometric group theory. Among the consequences of his work are a proof that the class of finitely generated, torsion-free hyperbolic groups is closed under elementary equivalence, and a proof that any two nonabelian free groups are elementarily equivalent.
2003 Karp Prize
Gregory Hjorth, UCLA and Alexander Kechris, Caltech
The sixth Karp Prize was awarded at the ASL Annual Meeting to Gregory Hjorth and Alexander Kechris for their recent work on Borel equivalence relations, in particular for their results on turbulence and countable Borel equivalence relations.
Ehud Hrushovski, Hebrew University
The recipient of the 1998 Karp Prize of the Association for Symbolic Logic was Ehud Hrushovski of the Hebrew University, Jerusalem, for his work on the Mordell-Lang Conjecture. This award was made by the Association on recommendation of the ASL Committee on Prizes and Awards.
Ehud Hrushovski, MIT and Alex Wilkie, Oxford
The ASL Committee on Prizes and Awards selected Ehud Hrushovski, MIT, and Alex Wilkie, Oxford, as the recipients of the 1993 Karp Prize. Hrushovski was honored for his introduction of new methods in geometric stability theory; Wilkie was honored for proving the model completeness of the field of real numbers with the exponential function. The two prizes were awarded at a special session at the ASL Annual Meeting in March, at which John Baldwin and Angus Macintyre gave talks which summarized the accomplishments for which Hrushovski and Wilkie were being honored.
Donald A. Martin, UCLA, John R. Steel, UCLA, and W. Hugh Woodin, University of California, Berkeley
The ASL Committee on Prizes and Awards selected Donald A. Martin, UCLA, John R. Steel, UCLA, and W. Hugh Woodin, University of California, Berkeley as the recipients of the 1988 Karp Prize, "for their work establishing from the existence of a supercompact cardinal that the Axiom of Determinacy holds in the smallest transitive model of ZF containing all reals and all ordinals."
Saharon Shelah, Hebrew University
The 1983 Karp Prize was awarded to Saharon Shelah of the Hebrew University of Jerusalem, Israel, for his work on the number of nonisomorphic models of first order theories.
Robert Vaught, University of California, Berkeley
