Spectral Barron spaces of periodic functions

Mourad Choulli, Shuai Lu, Hiroshi Takase

Spectral Barron spaces are Fourier-Lebesgue-type spaces that arise in the approximation of functions by neural networks. Conventional spectral Barron spaces are mostly considered o…

Heat equations in spectral Barron spaces

Mourad Choulli, Shuai Lu, Hiroshi Takase

Spectral Barron spaces, characterized by an \(L^1\)-based Fourier-Lebesgue norm, have earned significant attention in approximation theory due to their remarkable capacity to repre…

Determination of separable perturbations of an unbounded potential in the two-dimensional Schrödinger equation

Mourad Choulli, Hiroshi Takase

We establish uniqueness and stability results for a class of perturbations of an unbounded potential in the two-dimensional Schrödinger equation, from the corresponding Dirichlet-t…

An - Carleman inequality for

Mourad Choulli, Hiroshi Takase

In this note, by refining the proof of the Carleman inequality obtained by Dos Santos, Kenig, and Salo in 2013, we establish a new - Carleman inequality.

Quantitative Borg-Levinson theorem for the magnetic Schödinger operator with unbounded electrical potential

Mourad Choulli, Hiroshi Takase

The first author established in [8] a quantitative Borg-Levinson theorem for the Schrödinger operator with unbounded potential. In the present work, we extend the results in [8] to…

Inverse spectral problems for higher-order coefficients

Mourad Choulli

We establish uniqueness and stability inequalities for the problem of determining the higher-order coefficients of an elliptic operator from the corresponding boundary spectral dat…
