本文推广了2+1维Dym方程，通过Painlevé II对称性约化，求解了广义Stefan型移动边界问题。
AI 中文摘要
本文提出了对Konopelchenko和Dubrovsky最初引入的规范2+1维孤子Dym方程的一种带时间调制的推广。利用所允许的Painlevé II对称性约化，推导出一类相关的2+1维广义Stefan型非线性移动边界问题的精确解。
英文摘要
An extension with temporal modulation is presented of the canonical 2 + 1-dimensional solitonic Dym equation as originally introduced by Konopelchenko and Dubrovsky. Application is made of admitted Painleve' II symmetry reduction to derive exact solution to a class of associated 2 + 1-dimensional nonlinear moving boundary problems of generalized Stefan-type.
