Paul Biran

Ian Paul Biran (Hebrew פאול בירן; born February 25, 1969 in Bucharest ) is an Israeli mathematician who deals with symplectic geometry and topology and algebraic geometry.

Biran in 1971 came to Israel. After five years of military service from 1987 to 1992 he studied at the University of Tel Aviv (where incidentally he worked as a computer programmer at the company cfax ), where he received his doctorate in 1997 with Leonid Polterovich ( Geometry of symplectic packing ). 1997 to 1999 he was Szegö Assistant Professor at Stanford University. After that, he was a lecturer at the University of Tel Aviv, since 2005 Associate Professor and Professor in 2008. Since 2009, Paul Biran has been a Professor of Mathematics at the ETH Zurich.

He broke in his dissertation the ( already by Mikhail Gromov and other treated ) packing problem for symplectic 4 -manifolds ( he proved that this fully with balls of the same diameter can be filled, if the number of balls is large enough). He also introduced a new decomposition techniques for symplectic manifolds.

In 1998 he received the Research Award Landau. In 2003 he received the Oberwolfach Prize. In 2004 he was awarded the EMS price ( Price talk: Symplectic topology and algebraic families ). In 2002 he was invited speaker at the International Congress of Mathematicians (ICM ) in Beijing ( Geometry of symplectic intersections ). In 2006 he received the Erdős Prize. In 2013 he was elected to the Leopoldina.
