闭子集 meaning in English
closed set
closed subset
Examples
- We show that if f is positively expansive and has the potp , then there is no proper nonempty invariant subset of basic sets in which f has the potp
如果它还是正向膨胀的，则链分支中不存在真闭子集保持伪轨跟踪性。 - Besides the existence , this essay also draws the conclusion that the optimal income tax function is lowers semicontinuous on a closed subset of the hilbert space
除了存在性，本文还得出了最优收入税函数在hilbert空间的一个闭子集上是下半连续的结论。 - A time scale t is an arbitrary nonempty closed subset of the real numbers . in the paper , we study quasilinearization and the monotone iteration methods for second - order nonlinear boundary value problems on time scales
时间模t _ 1是实数集上的一个非空闭子集，本文讨论了时间模上二阶非线性边值问题的拟线性方法和单调迭代方法。 - Reich [ 2 ] proved the ergodic theorems to nonexpansive semigroups in hilbert spaces . takahashi and zhang [ 3 ] , tan and xu [ 4 ] extended baillon ' s theorem to asymptotically nonexpansive and asymptotically nonexpansive type semigroups in hilbert spaces . recently , reich [ 6 ] , bruck [ 5 ] , oka [ 7 ] gave the ergodic convergence theorems for nonexpansive , asymptotically nonexpansive mappings and semigroups in uniformly convex banach spaces with frechet differentiable norm . li and ma [ 13 ] obtained the ergodic convergence theorems for general commutative asymptotically nonexpansive type topological semigroups in reflexive banach space , which is a great breakthrough
Baillon [ 1 ]首先在hilbert空间的非空凸闭子集上给出了非扩张映照的弱遍历收敛定理。 baillon的定理引起了很多数学家的兴趣， reich [ 2 ]在hilbert空间中证明了非扩张半群的遍历收敛定理。 takahashi和zhang [ 3 ] ， tan和xu [ 4 ]分别将baillon的定理推广到渐近非扩张半群及渐近非扩张型半群。
