# Operator Theory and Its Applications

*A. G. Ramm; P. N. Shivakumar; A. V. Strauss*

A co-publication of the AMS and Fields Institute

This volume contains a selection of papers presented at an
international conference on operator theory and its applications held
in Winnipeg. The papers chosen for this volume are intended to
illustrate that operator theory is the language of modern analysis and
its applications. Together with the papers on the abstract operator
theory are many papers on the theory of differential operators,
boundary value problems, inverse scattering and other inverse
problems, and on applications to biology, chemistry, wave propagation,
and many other areas.

The volume is dedicated to the late A. V. Strauss, whose principal
areas of research were spectral theory of linear operators in Hilbert
spaces, extension theory for symmetric linear operators, theory of the
characteristic functions and functional models of linear operators,
and boundary value problems with boundary conditions depending on
spectral parameter. The bibliography of publications by A. V. Strauss
combined with the papers from the conference provide both historical
perspective and contemporary research on the field of operator theory
and its applications.

Titles in this series are co-published with the Fields Institute for Research in Mathematical Sciences (Toronto, Ontario, Canada).
