《界面与自由边界》致力于对界面和自由边界问题进行数学建模、分析和计算，并在与这些现象相关的所有领域进行研究。该杂志旨在成为一个论坛，在那里，数学分析，偏微分方程，建模，科学计算和各种应用，涉及数学建模满足。理想情况下，提交的报告应强调理论和应用的结合。
Interfaces and Free Boundaries is dedicated to the mathematical modelling, analysis and computation of interfaces and free boundary problems in all areas where such phenomena are pertinent. The journal aims to be a forum where mathematical analysis, partial differential equations, modelling, scientific computing and the various applications which involve mathematical modelling meet. Submissions should, ideally, emphasize the combination of theory and application.
