Jürg Peter Buser
Jürg Peter Buser, known as Peter Buser, is a Swiss mathematician, specializing in differential geometry and global analysis.Education and career
Buser received his doctorate in 1976 from the University of Basel with advisor Heinz Huber and thesis Untersuchungen über den ersten Eigenwert des Laplaceoperators auf kompakten Flächen. As a post-doctoral student he was at the University of Bonn, the University of Minnesota. and the State University of New York at Stony Brook, before he habilitated at the University of Bonn with a thesis on the length spectrum of Riemann surfaces.
Buser is known for his construction of curved isospectral surfaces. His 1988 construction led to a negative solution to Mark Kac's famous 1966 problem Can one hear the shape of a drum?. The negative solution was published in 1992 by Scott Wolpert, David Webb and Carolyn S. Gordon. The is named after him and Jeff Cheeger.
He has been a professor at the École Polytechnique Fédérale de Lausanne since 1982. From 2004 to 2005 he was president of the Swiss Mathematical Society. In 2003 he was made an honorary doctor of the University of Helsinki.Selected publications
