Properties of Sturm-Liouville Eigenfunctions and Eigenvalues

Real Eigenvalues Just as a symmetric matrix has real eigenvalues, so does a (self-adjoint) Sturm-Liouville operator. Proposition 2 The eigenvalues of a regular or periodic Sturm-Liouville problem are real.

The following essential result characterizes the behavior of the entire set of eigenvalues of Sturm-Liouville problems. Proposition 6 The set of eigenvalues of a regular Sturm-Liouville problem is countably in nite, and is a monotonically increasing sequence 0 < 1 < 2 < < n< n+1 < with lim n!1 n = 1. The same is true for a periodic Sturm ...

We de ne a second-order linear di erential operator Lby L[y] = y00+ p(t)y0+ q(t)y: Then, a initial value problem with a second-order homogeneous linear ODE can be stated as L[y] = 0; y(t 0) = y 0; y0(t 0) = z 0: We state a result concerning existence and uniqueness of solutions to such ODE, analogous to the Existence-Uniqueness Theorem for rst ...

Linear Interpolating Splines - USM

Linear Interpolating Splines We have seen that high-degree polynomial interpolation can be problematic. However, if the tting function is only required to have a few continuous derivatives, then one can construct a piecewise polynomial to t the data. We now precisely de ne what we mean by a piecewise polynomial.

(We do specify that R remain finite.) We do need a boundary condition at ρ= a. It is simpler and more elegant to solve Bessel’s equation if we change ...
