Summary: The \(L^p\) well-posedness for the complex Ginzburg-Landau equation \(\partial u/\partial t- (\lambda+i\mu)\Delta u+ (\kappa+i\nu)|u|^{q-2}u-\gamma u=0\) in \(\Omega\times(0,\infty)\) with Dirichlet boundary condition \(u=0\) on \(\partial\Omega\times(0,\infty)\) is studied under the assumption that \(|\mu|/\lambda< 2\sqrt{p-1}/|p-2|\) and \(2\leq q\leq 2+2p/N\). The result due to Ginibre and Velo is improved in that the obtained solution is of class \(C^1\), the Lipschitz continuous dependence of solutions on their initial data is obtained and their result remains true even if \(1<p<2\) and \(\Omega\) is a general domain in \(\mathbb R^N\) with smooth boundary.
