两相Stefan问题的黏性解

Viscosity Solutions for the two-phase Stefan Problem

Inwon C. Kim, Norbert Pozar

摘要:

我们引入了一个概念的黏性解的两相Stefan问题,其中包括可能存在的糊状区域所产生的初始数据。我们证明了黏性解之间存在一个比较原理,并研究了黏性解与通过分部积分法定义的弱解的一致性。特别地,在没有初始糊状区的情况下,黏性解是具有相同边界数据的唯一弱解。

英文摘要:

We introduce a notion of viscosity solutions for the two-phase Stefan problem, which incorporates possible existence of a mushy region generated by the initial data. We show that a comparison principle holds between viscosity solutions, and investigate the coincidence of the viscosity solutions and the weak solutions defined via integration by parts. In particular, in the absence of initial mushy region, viscosity solution is the unique weak solution with the same boundary data.
