On the concatenability of solutions of partial differential equations

Sara Maad Sasane, Amol Sasane

Let $D^{'} (R^{d})$ denote the space of distributions on $R^{d}$ . For a linear partial different equation $p(\frac{\partial}{\partial x_1},\cdots, \frac{\…

Embedded eigenvalues for asymptotically periodic ODE systems

Sara Maad Sasane, Wilhelm Treschow

We investigate the persistance of embedded eigenvalues under perturbations of a certain self-adjoint Schrödinger-type differential operator in $L^{2} (R; R^{n})$ , with…

Perturbations of embedded eigenvalues for self-adjoint ODE systems

Sara Maad Sasane, Alexia Papalazarou

We consider a perturbation problem for embedded eigenvalues of a self-adjoint differential operator in $L^{2} (R; R^{n})$ . In particular, we study the set of all small pe…

Monotone smoothing splines with bounds

Sara Maad Sasane

The problem of monotone smoothing splines with bounds is formulated as a constrained minimization problem of the calculus of variations. Existence and uniqueness of solutions of th…

Perturbations of embedded eigenvalues for the planar bilaplacian

Gianne Derks, Sara Maad Sasane, Bjorn Sandstede

Operators on unbounded domains may acquire eigenvalues that are embedded in the essential spectrum. Determining the fate of these embedded eigenvalues under small perturbations of…

Persistence of embedded eigenvalues

Shmuel Agmon, Ira Herbst, Sara Maad Sasane

We consider conditions under which an embedded eigenvalue of a self-adjoint operator remains embedded under small perturbations. In the case of a simple eigenvalue embedded in cont…
