Affine section tomography for inverse source problems in -Hessian equations with restricted large boundary data

Yi-Hsuan Lin

We consider an inverse source problem for the -Hessian equation \begin{equation*} σ_k(D^2u)=f(x) \end{equation*} on the -admissible branch in a smooth uniformly convex domai…

An inverse source problem for a fully nonlinear elliptic equation

Ching-Lung Lin, Yi-Hsuan Lin, Jenn-Nan Wang

We study an inverse source problem for fully nonlinear elliptic equations of the form \[ F(D^2u)=f \quad \text{in } Ω. \] The question is whether the source term can be recovered…

Recovering stable kernels from exterior measurements

Yi-Hsuan Lin

We study an inverse problem for translation-invariant symmetric stable operators of the form \begin{equation*} L_a u(x)=\mathrm{P.V.}\int_{\mathbb R^n}(u(x)-u(y))\frac{a((x-y)/|x-y…

Entanglement principle for fractional Laplacian on hyperbolic spaces and applications to inverse problem

Yi-Hsuan Lin

We establish an entanglement principle for fractional powers of the Laplace-Beltrami operator on hyperbolic space , . More precisely, we prove that if finitely…

Finite element error analysis for elliptic parameter identification with power-type nonlinearity

De-Han Chen, Yi-Hsuan Lin, Irwin Yousept

This paper studies the numerical analysis of a parameter identification problem governed by elliptic equations with power-type nonlinearity. We propose a numerical reconstruction v…
