摘要
本文研究了二重序列(xkl)的空间ece，对某数a满足lim l lim k |xkl a|=0。本文利用滑动驼峰参数，给出了三维矩阵(sm -方法)将每一个收敛或有界序列(xk)变换到空间Ce或Cbe的充分必要条件，即Ce中列有界的元素空间。
We study the spaceCe of double sequences(xkl), satisfying lim l lim k |xkl a|=0 for some number a. In this note, using gliding hump arguments, we give necessary and sufficient conditions for a 3-dimensional matrix (i.e. SM-method) to transform every convergent or bounded sequence (xk) into the space Ce or Cbe, the space of elements in Ce with bounded columns.
