Kruskal-Segur方法的选择理论在扩散限制或拉普拉斯增长的扩展通过结合Zauderer分解方案。这样,非线性体方程变得易于处理。为了证明该方法,我们将其应用到二维晶体生长的势流。我们省略了简化近似用于同一系统的初步计算[Fischaleck,Kassner,Europhys。Lett. 81,54004(2008)EULEEJ 0295 -507510.1209/0295-5075/81/54004],从而展示了该方法将数学严谨性扩展到比迄今为止可获得的更复杂问题的能力。
The Kruskal-Segur approach to selection theory in diffusion-limited or Laplacian growth is extended via combination with the Zauderer decomposition scheme. This way nonlinear bulk equations become tractable. To demonstrate the method, we apply it to two-dimensional crystal growth in a potential flow. We omit the simplifying approximations used in a preliminary calculation for the same system [Fischaleck, Kassner, Europhys. Lett. 81, 54004 (2008)EULEEJ0295-507510.1209/0295-5075/81/54004], thus exhibiting the capability of the method to extend mathematical rigor to more complex problems than hitherto accessible.
