Sturm-Liouville problems with transfer condition Herglotz dependent on the eigenparameter -- Hilbert space formulation

Casey A. Bartels, Sonja Currie, Marlena Nowaczyk +1

We consider a Sturm-Liouville equation $\ell y:=-y^{\prime \prime }+qy=\lambda y$ on the intervals $(-a,0)$ and $(0,b)$ with $a,b>0$ and $q\in L^2(-a,b)$. We impose boundary conditions $y(-a)\cosα=…
