Subject: New Memoir on Spectral Theory and Orthogonal Polynomials

The following AMS Memoir appeared:

A. Jirari,
"Second-order Sturm-Liouville equations and orthogonal polynomials",
Memoirs AMS, Vol. 113, Number 542, 1995.

From the abstract:
The book develops a theory for regular and singular Sturm-Liouville
boundary problems for difference equations, generalizing many of the
known results for differential equations.
Discussing the self-adjointness of these problems as well as their
abstract spectral resolution in the appropriate $L^2$ setting.
the book gives necessary and sufficient conditions for a second-order
difference operator to be self-adjoint and have orthogonal polynomials
as eigenfunctions.
