Abstract: The asymptotic behavior of a nonlocal Ginzburg-Landau equation

$\displaystyle u_t^\varepsilon = \Delta {u^\varepsilon } - \frac{1}{{{\varepsilo... ...\frac{1}{\varepsilon }g\left( {{u^\varepsilon }} \right){\lambda ^\varepsilon }$

is studied when the small parameter $ \varepsilon $ tends to zero. Here a Lagrange multiplier $ {\lambda ^\varepsilon }$ is introduced into the equation to enforce the conservation of mass. An energy-estimates approach is used to show that a limiting solution can be characterized by moving interfaces. It is further shown that the asymptotic limit of solutions of the nonlocal Ginzburg-Landau equation is a weak solution of the nonlocal, mass-preserving mean curvature flow. The weak solutions are constructed within a framework of the theory of viscosity solutions. In addition, the results describing interactions between the interfaces are obtained.
