We consider the spectral structure of second order boundary-value problems on graphs. A variational formulation for boundary-value problems on graphs is given. As a consequence we can formulate an analogue of Dirichlet-Neumann bracketing for boundary

We consider a Sturm–Liouville equation $$\ell y:=-y'' + qy = \lambda y$$ on the intervals $$(-a,0)$$ and (0, b) with $$a,b>0$$ and $$q \in L^2(-\,a,b)$$ . Boundary conditions $$y(-\,a)\cos \alpha = y'(-\,a)\sin \alpha $$ , $$y(b)\cos \beta =y'(b)\s

This paper inductively investigates an inverse problem for difference boundary value problems with boundary conditions that depend quadratically on the eigenparameter. In particular, given the eigenvalues and the weights, we provide an algorithm to u

Assume the eigenvalues and the weights are given for a difference boundary value problem and that the form of the boundary conditions at the endpoints is known. In particular, it is known whether the endpoints are fixed (i.e. Dirichlet or non-Dirichl

The following inverse problem is solved—given the eigenvalues and the potential b(n) for a difference boundary value problem with quadratic dependence on the eigenparameter, λ, the weights c(n) can be uniquely reconstructed. The investi-gation is
