摘要
我们考虑定义在单位球面 上的概率密度函数上的自由能泛函,并研究其全局最小解。该能量由两个组成部分构成:熵项和非局部相互作用能,分别偏好扩散和聚集行为。我们发现吸引相互作用规模的阈值,并在不同情况下的建立全局能量最小解。我们研究该阈值处的分岔现象。我们还推广结果至由任意数量球体组成的空间(例如平面环面 )。

I noticed that the same research has been done by other researchers after the submission. Since I did not cited the work of related work, I would like to withdraw this paper
