本文研究了在Möbius空间中平滑浸入的等温表面。通过对杜平环面的达布变换的分析,找到了两种系统中具有球面曲率线的非特殊、非管状等温环面的明确例子。此外,用微分方程描述了等温浸没时球面曲率线的Calapso势的性质,并探讨了经典变换对这一性质的影响。
This article examines isothermic surfaces smoothly immersed in Möbius space. It finds explicit examples of non-special, non-canal isothermic tori with spherical lines of curvature in two systems by analyzing Darboux transforms of Dupin tori. In addition, it characterizes the property of spherical lines of curvature in terms of differential equations on the Calapso potential of the isothermic immersion, and investigates the effect of classical transformations on this property.
