WebIn this paper, we study a singular Sturm–Liouville problem with an eigenparameter-dependent boundary condition and transmission conditions at two interior points. Using an operator-theoretical formulation, we transfer the problem to an operator in an appropriate Hilbert space. It is proved that the operator is self-adjoint. We also give the asymptotic … WebJul 4, 2024 · This is most easily done by developing a mathematical tool called Sturm-Liouville theory. It starts from an equation in the so-called self-adjoint form. where λ is a number, and r(x) and s(x) are greater than 0 on [a, b]. We apply the boundary conditions. with a1 and a2 not both zero, and b1 and b2 similar. WebON STURM'S SEPARATION THEOREM BY PAUL R. BEESACK 1. Introduction. The purpose of this note is to obtain an extension of the classical Sturm separation theorem for the second order, linear selfadjoint differential equation (1) (r/ï+sy = 0, to the case of a noncompact interval.
