曲率正则化各向异性表面扩散三维弹性薄膜的运动
Motion of three-dimensional elastic films by anisotropic surface diffusion with curvature regularization
摘要：
在三维外延应变薄膜中，证明了曲率正则化的表面扩散发展方程的短时存在性。这是通过实施一个最小化的运动计划，这是铰链上的$H^{-1}$梯度流结构的演变规律的基础。长时间的行为和李雅普诺夫稳定性的情况下，初始数据接近一个平坦的配置也解决了。
英文摘要：
Short time existence for a surface diffusion evolution equation with curvature regularization is proved in the context of epitaxially strained three-dimensional films. This is achieved by implementing a minimizing movement scheme, which is hinged on the $H^{-1}$-gradient flow structure underpinning the evolution law. Long-time behavior and Liapunov stability in the case of initial data close to a flat configuration are also addressed.
