An inverse nodal problem for vectorial Sturm-Liouville equations

Inverse Problems, 2000
The \(n\)-dimensional Sturm-Liouville problem \[ y''(x)+(\lambda I_n-P(x))y(x)=0,\;y(0)=y(1)=0, \tag{1} \] is considered, where \(P(x)\) is a continuous symmetric \(n\times n\) matrix-valued function defined on \([0,1]\). Let \(y\) be a continuous vector-valued function. Then \(x\) is called a nodal point of \(y(x)\) if \(y(x)=0\).

Inverse Nodal Problem For An Integro-Differential Operator

2015
In this study, we consider an inverse nodal problem of recovering integro-differential operatorwith the Sturm-Liouville differential part and the integral part of Volterra type. Furthermore, we obtain areconstruction formula for function M. So, we reconstruct the operator L with a dense subset of nodal pointsprovided that the function q is known.
