How do you solve the Sturm-Liouville problem?

These equations give a regular Sturm-Liouville problem. Identify p,q,r,αj,βj in the example above. y(x)=Acos(√λx)+Bsin(√λx)if λ>0,y(x)=Ax+Bif λ=0. Let us see if λ=0 is an eigenvalue: We must satisfy 0=hB−A and A=0, hence B=0 (as h>0), therefore, 0 is not an eigenvalue (no nonzero solution, so no eigenfunction).

What is a Sturm-Liouville eigenvalue problem?

The problem of finding a complex number µ if any, such that the BVP (6.2)-(6.3) with λ = µ, has a non-trivial solution is called a Sturm-Liouville Eigen Value Problem (SL-EVP). Such a value µ is called an eigenvalue and the corresponding non-trivial solutions y(.; µ) are called eigenfunctions.

How do you find the eigenvalues in Sturm-Liouville?

(p(x)y′)′ + (q(x) + λr(x))y = 0, a < x < b, (plus boundary conditions), is called an eigenfunction, and the corresponding value of λ is called its eigenvalue. The eigenvalues of a Sturm-Liouville problem are the values of λ for which nonzero solutions exist.

What is Sturm-Liouville differential equation?

In mathematics and its applications, classical Sturm–Liouville theory is the theory of real second-order linear ordinary differential equations of the form: (1) for given coefficient functions p(x), q(x), and w(x) and an unknown function y of the free variable x.

What is a regular Sturm-Liouville problem?

on an interval [a, b] is a SL differential equation. are called periodic boundary conditions. with p(x) > 0 and ω(x) > 0 for x ∈ [a, b] is called as regular Sturm-Liouville system (or problem). yλ and its derivative are continuous on [a, b], which also means these are bounded.

What is eigenvalue Schrodinger equation?

The term eigenvalue is used to designate the value of measurable quantity associated with the wavefunction. If you want to measure the energy of a particle, you have to operate on the wavefunction with the Hamiltonian operator (Equation 3.3. 6).
