针对体积约束的平均曲率流,提出一种修正相场方程,相比经典非局部Allen-Cahn方程具有更好的体积保持性质。
摘要:
本文关注随时间变化的超曲面在体积约束下由平均曲率流驱动的运动。该运动的相场近似导致著名的非局部Allen-Cahn方程。这里我们提出该方程的一个修正版本,并证明即使在存在额外强迫项的情况下,它也比经典方程具有更好的体积保持性质。
英文摘要:
This paper is concerned with the motion of a time dependent hypersurface that evolves by mean curvature flow with a a volume constraint. Phase field approximation of this motion leads to the well known nonlocal Allen--Cahn equation. Here we propose a modified version of this equation, and we show that it has better volume preserving properties than the classical one, even in the presence of an additional forcing term.
