Beyond Consistent Scenarios: Deriving Indirect Influence, Transition Resistance, and Adjustment Dynamics

Andrew G. Ross, Julia Gershenzon, Andreas Kleefeld

Assessments of structural change and economic transition dynamics, such as those arising in the energy transition, depend on internally consistent qualitative scenarios specifying…

Factorization method for a simply supported obstacle from point source measurements via far--field transformation

Isaac Harris, Andreas Kleefeld

We consider an inverse shape problem for recovering an unknown simply supported obstacle in two dimensions from near--field point--source measurements for the biharmonic Helmholtz…

Bifurcations in Interior Transmission Eigenvalues: Theory and Computation

Davide Pradovera, Alessandro Borghi, Lukas Pieronek +1

The interior transmission eigenvalue problem (ITP) plays a central role in inverse scattering theory and in the spectral analysis of inhomogeneous media. Despite its smooth depende…

Analysis of the transmission eigenvalue problem for biharmonic scattering considering penetrable scatterers

Rafael Ceja Ayala, Isaac Harris, Andreas Kleefeld

In this paper, we provide an analytical study of the transmission eigenvalue problem in the context of biharmonic scattering with a penetrable obstacle. We will assume that the und…

Existence of transmission eigenvalues for biharmonic scattering by a clamped planar region

Isaac Harris, Andreas Kleefeld, Heejin Lee

In this paper, we study the so-called clamped transmission eigenvalue problem. This is a new transmission eigenvalue problem that is derived from the scattering of an impenetrable…

Direct and inverse scattering for an isotropic medium with a second-order boundary condition

Govanni Granados, Isaac Harris, Andreas Kleefeld

We consider the direct and inverse scattering problem for a penetrable, isotropic obstacle with a second-order Robin boundary condition, which asymptotically models the delaminatio…
