DESCRIPTION:Evans Harrell (Georgia Institute of Technology)\nThe average o
 f the first k eigenvalues of a self-adjoint operator\, as a function of k
 \, has implications for inverse problems.  What information does it conta
 in about an operator\, or about the shape of a domain or graph on which th
 e operator is defined?  I'll describe some recently developed tools for a
 pproaching inverse problems through averages of eigenvalues\, with selecte
 d applications to PDEs on domains and manifolds and to graphs.  This work
  is joint with J. Stubbe of EPFL and\, in part\, A. El Soufi and S. Il
 ias of the University of Tours\, and J. Dever of Georgia Tech.
