## Uniform well-posedness for a time-dependent Ginzburg-Landau model in superconductivity.(English)Zbl 1420.35393

Summary: We study the initial boundary value problem for a time-dependent Ginzburg-Landau model in superconductivity. First, we prove the uniform boundedness of strong solutions with respect to diffusion coefficient $$0 < \epsilon < 1$$ in the case of Coulomb gauge. Our second result is the global existence and uniqueness of the weak solutions to the limit problem when $$\epsilon=0$$.
