Convergence of the parabolic Ginzburg-Landau equation to motion by mean curvature. (English) Zbl 1103.35038

The paper considers the initial-value problem for the multidimensional Ginzburg-Landau equation with real coefficients (but for a complex function). A theorem is rigorously proven that states that, asymptotically at \(t\to\infty\), the vorticity of the generic solution evolves in time according to the motion by mean curvature (in the special weak formulation introduced by K. A. Brakke [The motion of a surface by its mean curvature. Princeton, New Jersey: New Jersey University Press (1978; Zbl 0386.53047)], which allows one to encompass possible singularities of the solution). The only essential assumption used for the proof is a natural bound on the value of “energy” (in fact, Lyapunov’s functional) of the initial data.
