Stability estimate for an inverse problem for the Schr{\"o}dinger   equation in a magnetic field with time-dependent coefficient
  We study the stability issue in the inverse problem of determining the magnetic field and the time-dependent electric potential appearing in the Schr\"odinger equation, from boundary observations. We prove in dimension 3 or greater, that the knowledge of the Dicrichlet-to-Neumann map stably determines the magnetic field and the electric potential.
