非空子集[fēi kōng zǐ jí]
  1. v'是v的一个非空子集。

    V'is a nonempty subset of V.

  2. 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.

  3. 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 .
