An inverse source problem for the Monge--Ampere equation from large boundary data

Cătălin I. Cârstea, Tuhin Ghosh

We study an inverse source problem for the Monge--Ampere equation \[ \det D^2u=f(x) \] on a bounded smooth uniformly convex domain. In the smooth classical regime, we prove that th…

Inverse boundary value problems for certain doubly nonlinear parabolic and elliptic equations

Cătălin I. Cârstea, Tuhin Ghosh

We consider an inverse boundary value problem for the doubly nonlinear parabolic equation \[ ε(x)\partial_t u^m-\nabla\cdot\bigl(γ(x)|\nabla u|^{p-2}\nabla u\bigr)=0 \quad\text{i…

Inverse scattering for the fractional Schrödinger equation

Saumyajit Das, Tuhin Ghosh, Shiqi Ma

This article is devoted to studying the inverse scattering for the fractional Schrödinger equation, and in particular we solve the Born approximation problem. Based on the (,

Fractional Borg-Levinson Problem with small non-negative potential of small growth

Saumyajit Das, Tuhin Ghosh

In this article, we investigate the fractional Borg-Levinson problem, an inverse spectral problem focused on recovering potentials from boundary spectral data. We demonstrate that…
