asymptotic behavior of the solutions of the time-dependent
Ginzburg-Landau equations of superconductivity, in the case where
the applied magnetic field $\H$ is time-dependent. We first prove
existence and uniqueness of solutions with $H^1$-initial data.
This result is obtained under the ``$\phi=-\omega(\nabla\cdot\A)$''
gauge with $\omega>0$. These solutions become then uniformly
bounded in time for the $H^1$-norm, by assuming time-uniform
boundedness on $\H$ and its time derivative.
