讨论群G上的幂半群Г，即以G的非空子集为元素，在G的集的乘法运算下所成的幂半群。
Let Г be a power semigroup on a group G , that is all elements of Г are sub-sets of G and the operation is subset product of G.

提出完备空间（x，d）到其全部非空子集族B（x）的下半连续集值映射一条不动点定理，使Clarke[1]不动点定理成为这一定理的特例。
We indicate a no moving point theorem of complete space ( x , d ) to the last half continuous set magnitude mapping of its not empty subset group B ( x ), which makes the Clarke no moving point theorem become its exception .
