Rigidity of homogeneous Lamé systems

Joonas Ilmavirta, Teemu Saksala, Lili Yan

In this short paper, we show that any Lamé system whose Dirichlet-to-Neumann map for the elastic wave equation agrees with the one arising from the homogeneous Lamé system must a…

The higher-order fractional Schrödinger equation with nonlinear local perturbations: Uniqueness

Giovanni Covi, Ru-Yu Lai, Lili Yan

We study the higher-order fractional Schrödinger equation with local nonlinear perturbations and investigate both the forward and inverse problems. We establish both the Sobolev $…

Entanglement principle and fractional Calderón problem for nonlocal parabolic operators

Ru-Yu Lai, Yi-Hsuan Lin, Lili Yan

We examine inverse problems for the variable-coefficient nonlocal parabolic operator , where . This article makes two primary contributions. First…

Hölder stability of an inverse spectral problem for the magnetic Schrödinger operator on a simple manifold

Boya Liu, Hadrian Quan, Teemu Saksala +1

We show that on a simple Riemannian manifold, the electric potential and the solenoidal part of the magnetic potential appearing in the magnetic Schrödinger operator can be recove…

Partial data inverse problems for the nonlinear magnetic Schrödinger equation

Ru-Yu Lai, Gunther Uhlmann, Lili Yan

In this paper, we study the partial data inverse problem for nonlinear magnetic Schrödinger equations. We show that the knowledge of the Dirichlet-to-Neumann map, measured on an a…

Recovery of a time-dependent potential in hyperbolic equations on conformally transversally anisotropic manifolds

Boya Liu, Teemu Saksala, Lili Yan

We study an inverse problem of determining a time-dependent potential appearing in the wave equation in conformally transversally anisotropic manifolds of dimension three or higher…
