# Sturm-Liouville Operators and Applications: Revised Edition

*Vladimir A. Marchenko*

Translated by A. Iacob

The spectral theory of Sturm-Liouville operators is a classical domain of
analysis, comprising a wide variety of problems. Besides the basic results
on the structure of the spectrum and the eigenfunction expansion of
regular and singular Sturm-Liouville problems, it is in this domain that
one-dimensional quantum scattering theory, inverse spectral problems, and
the surprising connections of the theory with nonlinear evolution
equations first become related. The main goal of this book is to show what
can be achieved with the aid of transformation operators in spectral
theory as well as in their applications. The main methods and results in
this area (many of which are credited to the author) are for the first
time examined from a unified point of view.

The direct and inverse problems of spectral analysis and the inverse
scattering problem are solved with the help of the transformation
operators in both self-adjoint and nonself-adjoint cases. The asymptotic
formulae for spectral functions, trace formulae, and the exact relation
(in both directions) between the smoothness of potential and the
asymptotics of eigenvalues (or the lengths of gaps in the spectrum) are
obtained. Also, the applications of transformation operators and their
generalizations to soliton theory (i.e., solving nonlinear equations of
Korteweg-de Vries type) are considered.

The new Chapter 5 is devoted to the stability of the inverse
problem solutions. The estimation of the accuracy with which the
potential of the Sturm-Liouville operator can be restored from the
scattering data or the spectral function, if they are only known on a
finite interval of a spectral parameter (i.e., on a finite interval of
energy), is obtained.
