自Ilmanen的开创性工作[J. Differential Geom. 38, 417-461, (1993)]以来,理解耦合Allen-Cahn方程系统的尖锐界面极限一直是一个重大开放问题。我们首次证明了这类耦合系统的全局无条件收敛结果,并表明其极限是Brakke意义下的多相平均曲率流。
英文摘要
Since Ilmanen's pioneering work [J. Differential Geom. 38, 417-461, (1993)] it has been a major open problem to understand the sharp-interface limit of systems of coupled Allen-Cahn equations. We prove - for the first time - a global, unconditional convergence result for such a coupled system and show that the limit is a multiphase mean curvature flow in the sense of Brakke.
