Inverse problems for time-fractional Schrödinger equations

S. E. Chorfi, F. Et-tahri, L. Maniar +1

We study some inverse problems for time-fractional Schrödinger equations involving the Caputo derivative of fractional order $α \in (0, 1)$ . We prove refined uniqueness results from…

Forward and backward problems for abstract time-fractional Schrödinger equations

S. E. Chorfi, F. Et-tahri, L. Maniar +1

We investigate forward and backward problems associated with abstract time-fractional Schrödinger equations $i^{ν} \partial_{t}^{α} u (t) + A u (t) = 0$ , $α \in (0, 1) \cup (1, 2)$ and $ν…

Stability of backward-in-time semilinear coupled parabolic systems

S. E. Chorfi, M. Yamamoto

We consider backward problems for semilinear coupled parabolic systems in bounded domains. We prove conditional stability estimates for linear and semilinear systems of strongly co…
