摘要

利用一定序列的抛物正则化方法，建立了表面张力作用下Hele-Shaw单元中单相径向粘性指法问题（原问题）经典解的存在性\(\{\varepsilon_n\}_{n \in \mathbb{N}}\), \(\varepsilon_n>0\)。本文利用抛物正则化方法，对参数\(\{\varepsilon\}\), \(\varepsilon>0\)的全序列证明了原问题经典解的唯一性。

ON THE UNIQUENESS OF THE CLASSICAL SOLUTION OF THE FINGERING PROBLEM IN A HELE-SHAW CELL WITH SURFACE TENSION

The existence of a classical solution was established for a one-phase radial viscous fingering problem in a Hele-Shaw cell under surface tension (original problem) by means of parabolic regularization for a certain subsequence \(\{\varepsilon_n\}_{n \in \mathbb{N}}\), \(\varepsilon_n>0\). In this paper, we prove the uniqueness of the classical solution to the original problem with the use of parabolic regularization for the full sequence of the parameter \(\{\varepsilon\}\), \(\varepsilon>0\).
