本文研究了球上点涡的运动,并用线性代数的方法求出了相对平衡的对称位形。此外,我们给出了一个基于正多面体的对称构型目录。最后,我们研究了平衡构型的稳定性。
We study the motion of point vortices on a sphere and, using the methods of linear algebra, find the symmetric configurations of relative equilibrium. Furthermore, we give a catalog of symmetric configurations based on regular polyhedrons. Finally, we investigate the stability of the equilibrium configurations found.
