Inversion of Discrete Second-Order Systems, properties of the solution of, and the inverse problems for, the Sturm-Liouville equation (see Chapter 8), and the discrete problems were studied because such problems were met in any approximate analysis of Sturm-Liouville problems. Krein’s early papers (1933, 1934) concern the theory of Sturm seq

The Inverse Problem for the Discrete Vibrating Beam, Section 2.3. This model is important because it is the simplest model — it is in effect a finite-difference approximation — for a beam with continuously distributed mass. The inverse problem for a continuous beam will be considered in Chapter 10. The inverse problem for a discrete beam was first co

In the first three sections of this chapter we shall state the governing differential equations, discuss some transformations linking them, derive some elementary properties of their solutions, and fo
