Stability for a magnetic Schrödinger operator on a Riemann surface with boundary

Joel Andersson, Leo Tzou

We consider a magnetic Schrödinger operator $(\nabla^{X})^{*} \nabla^{X} + q$ on a compact Riemann surface with boundary and prove a $lo g lo g$ -type stability estimate in terms of Cauchy da…

Stability estimates with a priori bound for the inverse local Radon transform

Joel Andersson, Jan Boman

We consider the inverse problem for the $2$ -dimensional weighted local Radon transform $R_{m} [f]$ , where $f$ is supported in $y \geq x^{2}$ and $R_m[f](ξ,η)=\int f(x, ξx + η) m(ξ, η, x)…

On the Theorem of Uniform Recovery of Random Sampling Matrices

Joel Andersson, Jan-Olov Strömberg

We consider two theorems from the theory of compressive sensing. Mainly a theorem concerning uniform recovery of random sampling matrices, where the number of samples needed in ord…
