An application of the functional-equation approach of dynamic programming to the study of variational problems associated with the Sturm-Liouville equation of second order with real coefficients. By obtaining the dependence of the Green's function on the interval length, the authors determine the corresponding dependence of the characteristic values and the characteristic functions, and similar results for vector-matrix systems. Min-max variation is used to apply the same general techniques to the study of equations with complex coefficients. It is shown that this method can be applied rigorously.

This report is part of the RAND paper series. The paper was a product of RAND from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
