Juerg Peter Buser

from Wikipedia, the free encyclopedia


Jürg Peter Buser , known as Peter Buser, (born February 27, 1946 in Basel-Land ) is a Swiss mathematician who deals with differential geometry and global analysis .

Buser received his doctorate in 1976 at the University of Basel under Heinz Huber ( investigations into the first eigenvalue of the Laplace operator on compact surfaces ). As a post-doctoral student he was at the University of Bonn , the University of Minnesota in Minneapolis and the State University of New York at Stony Brook before he completed his habilitation at the University of Bonn with a thesis on the length spectrum of Riemann surfaces.

Curved isospectral surfaces he constructed in three dimensions led to the negative solution of the Can you hear the shape of a drum problem by Mark Kac (which asks for a planar solution) by Scott Wolpert , David Webb and Carolyn Gordon in 1992. After him and Jeff Cheeger is the name of the Cheeger-Buser inequality .

He has been a professor at the École polytechnique fédérale de Lausanne (EPFL) since 1982 . From 2004 to 2005 he was President of the Swiss Mathematical Society. He is an honorary doctorate from the University of Helsinki (2003).
