Bernd Siebert (mathematician)
Bernd Siebert (born March 5, 1964 in Berlin-Wilmersdorf ) is a German mathematician who deals with algebraic geometry .
Life
Siebert studied mathematics at the University of Erlangen from 1984 , moved on to the University of Bonn in 1986 and to the University of Göttingen in 1987 , where he received his diploma with distinction from Hans Grauert in 1989 . Subsequently he was a doctoral candidate and research assistant in Göttingen . In 1992 he received his doctorate from Grauert ( fiber cycle spaces, geometric platification and meromorphic equivalence relations ). In 1993/94 he was at the Courant Institute , then moved to Bochum and was a visiting scholar at MIT in 1997/98 before completing his habilitation in Bochum in 1998 ( Gromov-Witten invariants for general symplectic manifolds ). As a DFG Heisenberg Fellow, he went to the University of Paris VI / University of Paris VII from 2000 to 2002 . In 2002 he was appointed professor at the Albert Ludwig University of Freiburg . In 2008 he was appointed to the University of Hamburg, where he continues to research and teach to this day. Since 2011 he has been the speaker of the Graduate School Mathematics Inspired by String Theory and QFT .
In his research, Bernd Siebert initially made contributions to the theory of the Gromov-Witten invariants . Around 2002, through his insights into logarithmic geometry, he entered an ongoing joint research program with Mark Gross , which resulted in work related to string theory ( mirror symmetry ) and tropical geometry .
In 2014 he and Mark Gross are invited speakers at the International Congress of Mathematicians in Seoul in the section Complex Geometry (Local mirror symmetry in the tropics). For 2016 both were awarded the Clay Research Award .
