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{in…

Anisotropic Calderón problem for a logarithmic Schrödinger operator of order $2 +$ on closed Riemannian manifolds

Saumyajit Das, Tuhin Ghosh, Susovan Pramanik

In this article, we study the anisotropic Calderón problems for the non local logarithimic Schrödinger operators $(- Δ_{g} + m) lo g (- Δ_{g} + m) + V$ with $m > 1$ on a closed, connected, smoot…

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…
