Numerical solutions to inverse nodal problems for the Sturm–Liouville operator and their applications.

In this paper, we apply numerical methods to study inverse nodal problems for the Sturm–Liouville operator. At first, we find an approximate function of the potential from the nodal points of the ( n + 1 ) -th eigenfunction and three constants via the ...

Regularized trace of the Sturm-Liouville operator with irregular boundary conditions

Electronic Journal of Differential Equations, 2009
We consider the spectral problem for the Sturm-Liouville equation with a complex-valued potential $q(x)$ and with irregular boundary conditions on the interval $(0,pi)$. We establish a formula for the first regularized trace of the this operator.

Explicit solutions for Sturm-Liouville operator problems (II).

, 1987
It is proved that the resolution problem of a Sturm-Liouville operator problem for a second-order differential operator equation with constant coefficients is solved in terms of solutions of the corresponding algebraic operator equation.
