摘要翻译：
研究了平面量子气体中一个和两个点状涡的动力学问题。找到了新的解析解和数值解。定义了与环空的双连通性有关的平稳性半径的概念。这些半径的存在对涡旋的行为有很大的影响。结果表明，由于定常半径的存在，无论涡旋数的符号如何，涡旋都表现出类似的行为。定性地研究了能量稳定涡解。

英文摘要：
The dynamics of one and two pointlike vortices in a planar quantum gas of spin-0 particles confined in an annular region is considered. New analytical and numerical solutions are found. The concept of stationarity radius, related to the doubly connected nature of the annulus, is defined. It is seen that the existence of these radii has great impact on the behaviour of the vortices. It is shown that, because of the existence of the stationarity radii, vortices exhibit similar behaviour regardless of the sign of their winding number. The energetically stable vortex solutions are studied qualitatively.
