摘要
关于自由边界,目前人们主要讨论一个障碍的问题,研究自由边界的确定和正规性。本文应用Lions的奇异摄动方法,讨论两个障碍的问题,研究自由边界之间的摄动关系和误差估计。
Recently, the research works in regard to the free-boundary problems are always concentrated in the fields of determinations and regularities of those with one obstacle. In this paper, the authors have discussed the free-boundary problems with two obstacles and obtained some interesting results among boundaries and of estimates.
