Abstract

In this chapter, we prove the Green’s function of a well-constrained beam to be an oscillatory kernel by verifying that the beam has the oscillatory properties in static deformation.

Fußnoten
1
A continuous function in the interval \( (0,l) \) can have only two types of zeroes: nodes and null anti-nodes. Based on the concept of the number of sign reversals of a function, the count of null anti-nodes has no contribution to the minimal number of sign reversals, but a null anti-node is treated as two distinct zeroes in the calculation of the maximal number of sign reversals. As a result, the count of nodes of a function in the interval \( (0,l) \) equals the minimal number of sign reversals, while the count of its zeroes, including those at the end points of the interval, is identical to the maximal number of sign reversals.
